{Posting here, as there's increasing interest in LTC GBs and there is no equivalent LTC GB forum available}
You asked for a Litecoin Group Buy or mining contracts...so we responded with a Litecoin Group Buy!
These are Group Buys to own fractional ownership of DZ MC Ultra Power Rigs capable of 3.6 to 4 MH/s in Scrypt hashrate. Each sub-round in R20 will Feature four (4) ATI Radeon R9 R290x GPUs with 4 GB of GDDR5 per GPU.
These are the Lamborghinis of the Scrypt mining world.This LTC GB is meant for those looking to diversify from BTC Buy/Hold, and BTC GBs into Litecoin GBs. Litecoin is now widely seen as the "Silver" to Bitcoin's "Gold"-like standard, and has had massive appreciation in value recently.
The network difficulty growth is also much lower in Scrypt mining.12/11 Clarification:
**
We will be doing multipool, even multi-coin mining. I listed this as an LTC GB but we will definitely be mining some of the better known ALT coins when it makes sense, as we're big fans of triangular arbitrage. Payouts will be in LTC (please leave your LTC wallet address for payouts in order comments or send a follow up support ticket) **
======================================================================================================
To reserve shares automatically and for easiest spreadsheet export,
please visit the new DZ Miner's Coop website.
======================================================================================================
25 shares are available in each rig. Each share gives you 1/25th of the rig's hashrate (minus low cost professional hosting/management fees).
If this GB sells out, we simply open up another sub-round called R20B. We can repeat this as needed, as R20x doesn't face the same hardware shortages that are often found in the ASIC Bitcoin miner world, since GPUs and PCs are essentially commodities at this time, as opposed to the prototypes we all get sent (AKA as ASIC miners). Inventory is essentially Unlimited for R20x, so there's no worries about running out of GB shares.
** Each user is limited to only 6 shares per rig/sub-round (6 shares in R20A, 6 shares in R20B, etc., etc.) so that other people get a chance to own a part of the rig, and so that too much ownership/votes don't reside in any one person's hands. Purchases of 6 or more shares will be automatically split amongst multiple GPU rigs/sub-rounds. **===

1 share = $212 = 144-160 KH/s for 6 months (unless there's a push from owners to sell the equipment earlier) + access to ultra low cost miner hosting at $300 per rig per month (and a 0.5% Management Fee). We will sell the unit or decide to continue running it before the 6 month mark.
This share price includes assembly/testing/troubleshooting & access to monthly low fixed costs for business insured hosting/management fees in a professional ASIC/GPU Miner Colocation Facility built just for LTC/BTC miners in conjunction with Miner Hosting LLC run by bobsag3.

[Per the rest of our other forum GBs, any resales at the 5-7 month mark will have the proceeds split by proportion to one's ownership of that Round's rig minus a 1.5% co-op transaction fee for handling this sale]
Share price includes funds to purchase an entire DZ MC LTC Ultra Power Rig, the assembly and testing, and UPS with battery backup. Hashrate will be split in 25 portions or GB shares.
Comparison: with shipping, an R9 R270x video card alone, capable of 450KH/s costs $220-260, before you factor in the rest of the system (case/PSU/RAM/CPU/accessories/assembly/testing/power/cooling) needed to set up and run a power hungry and noisy Litecoin/Alt-coin rig for months at a time.
Hosting and Management fees: $300 per rig per month + a 0.5% management fee, which works out to $12-13 per month per share (~$6 per share per bi-monthly payout on the 7th and 22nd (we alternates payouts with BTC rigs, which are paid on the 1st and 15th)).
DZ MC Exclusives include multiple Server class UPS units and battery banks, multiple gas generators, dedicated extra Air Conditioning plus access to 5 world class IT experts!
Note: For those wondering - R9 R280x GPUs are in too short supply at this time for us to have confidence that we'll be able to get these models in the volume we need, at the time of ordering. If R280x supplies appear to have greater supplies in January/February, then we may consider revamping future R20x- based GBs.

Individual purchases will be batch processed a few times a week. Please don't be alarmed if your order shows as Processing for a few days. We're still only 2 guys batch processing orders at this time and we're not at the point that we can hire someone yet just for order processing. Mahalo!
Please open a support ticket if you have concerns that your order didn't go thru after 48-72 hours. Also, please check our FAQ to see if your question has already been answered before sending a support ticket or forum PM. Cheers.
P.S.: Pictures included are representative, and may not represent the actual hardware used due to supply constraints. We may actually go to open case aluminum cases if we can secure enough stock.

Please contact to me for questions and payments or to manually confirm your reservations, but please open a support ticket after 48-72 hours if you have questions about a particular R20 order.
If you have questions about Round 20 unit hosting please contact bobsag3.Since this is a 3.6 - 4 MH/s rig, at 25 shares per rig, that works out to 144-160 KH/s per share for R20x. Unit will be hosted at bobsag3 at the world's lowest hosting/management fees, for a limited time. This should be assembled and built by January 15 (estimated). Incremental and monitored Overclocking will be implemented as we'll be keeping things nice and chilly.
Your share price includes acquisition of an estimated 20 minutes of UPS/Battery Backup + Gas Generator backup, included in the discounted share price to keep BTC flowing during: short outages (blackouts), voltage sags (brownouts), and voltage spikes, as well as to provide power filtering. The special purpose Gas Generators our co-op buying power allows us are meant for providing power during longer outages.

Once sales begin, Refunds are available up until unit ships at 1.5% restock fee.
We vote on all buying, shipping, and resale decisions as well as vote on the month to attempt equipment resales after 5-7 months of operations.
Vetted GB Coordinators are encouraged to team up to increase buying power and close out Group Buys quicker. All suggestions are welcome to help improve
our Co-operative.
