Outlining Goals:I am currently organizing a group purchase for Lancelot, dual FPGA boards that are available through CardReaderFactory. For those uniformed with the Lancelot boards they generate around 380 MH/s mining Bitcoin and other SHA256 alt coins using roughly 30 watts of electricity. Here is the original thread created by ngzhang with release information:
https://bitcointalk.org/index.php?topic=79835.0 . These products have been rereleased and are currently available. The company selling them has tiered pricing as follows:
Quantity / Price
1+ / $350 each
10+ / $300 each
100+ / $275 each
500+ / $260 each
The goal for the group purchase is to hit at least 100 units to hit the $275 price point.

Hello everybody!
My company, Black Arrow Software
http://www.blackarrowsoftware.com, has just started manufacturing Lancelot FPGAs ( 380Mh/sec - 400Mh/sec ).
The Lancelot device was developed by ngzhang. Details in this thread:
https://bitcointalk.org/index.php?topic=79835.0You can purchase it from our reseller's website:
http://www.cardreaderfactory.com/shop/lancelot.htmlPrice: $350 / pcs. Discounts available for more than 10 pcs.
A 10 Amperes power supply can power 4 devices. As you do not need 1 power supply for each device, we no longer include 1 power supply for each device so we can save on the shipping costs. Please order the power supply separately.
30/04/2013: Stock update:First batch ready. Will ship 2-4 May.
Second batch should be ready on 10 May.
30/04/2013: Performance update:Due to limited availability of -3N and -3 xilinx FPGA we will be using -2 chips too. We have tested them and have no impact in the performance of the boards (see picture below). If you really want -3 chips do let us know and we'll hold your order until we manage to get some -3 chips.
If you haven't place your order yet, please place your order online and
do _not_ pay for it. We will send you a payment reminder as soon as they are in stock.
Payment: We accept Bitcoin (price in Bitcoins will be calculated when you've paid the order at mtgox's rate), Western Union and Bank Transfer.
Shipping: We are based in Shenzhen, local pickup available. We can also ship worldwide with DHL, UPS and EMS. Shipping price depends on the destination and package weight. Our website is configured to charge $70 flat fee but we'll update this as soon as we hear back from DHL/UPS.

Fan is included. At the moment is quite big and we're looking into how improve this.
The default firmware is running at 200mhz. We've tried the v42b firmware but it's just reporting faster speeds and doing less work.
The power consumption is 30Watt / device.

How the Group Purchase Works:Upon confirming interest in 100+ units each member of the group buy will be asked to send the amount of satoshis (.0000000x) equal to the amount of units they would like from an address that would contain the funding necessary to pay for the units. I would then need each person to post or PM the payment address they used so I can associate a name with the address. At the point 100 units are confirmed I will create a sales order with CardReaderFactory. Upon receiving payment instructions from blackarrow / CardReaderFactory I will request payment from members to the unique wallet address for the group buy. I would then need each member to PM me their shipping information. When the units arrive I will open the box, separate the units, box them, weigh them, and estimate shipping. I will then PM each member of the group purchase and coordinate shipping services and payment for the shipping with them. If any members are semi local (within a few hours) to me I will offer delivery of the units for the cost of gas, a sub sammich, and $10. I can also offer proxy mining services with $0.08 / kwh and 2% for anyone that may be unable to get their units running right away.
------------------------------------------------------------------------------------------------
Example of How This Will Work for Members of the Group Purchase:1abcdefgpaymentaddress
1. A user is interested in 10 units. That user would sent .00000010 BTC to the payment address. Then they would either post that, "I sent the coins to the address from 1exampleaddress" or PM Beaflag VonRathburg that information directly so the payment can be coordinated with the user.
2. Beaflag VonRathburg will create a sales order with CardReaderFactory upon reaching 100+ units.
3. The user will send payment and shipping information through PM to Beaflag VonRathburg
4. Units will be paid for.
5. Units ship to Beaflag VonRathburg
6. Beaflag VonRathburg separates units into individual orders and contacts group purchase members to coordinate shipping / delivery.
