Avalon renamed themselves to Canaan Creative after their Gen 1 shit-storm.

Irrespective of history, the current Avalon products are not price/performance competitive, at all, with SPTech or Bitmain.

Have you really been far even as decided to use even go want to do look more like ?

Facepalm^∞

I don't think that it has sunk in with you yet, that this community is entirely hostile to the concept of pre-orders.

If you don't have a product to demonstrate, offer specific technical data, or have established the ability to ship orders to customers within a week of taking payment, then I hope you can appreciate we aren't buying what you are selling.

No self-respecting, legitimate enterprise in Bitcoin space should expect to have a warm reception to pre-orders. You can thank companies such as Avalon, Butterfly Labs, KNC, Black Arrow, and others for teaching us to avoid pre-orders entirely.

Please come back when you have something to demonstrate, and are able to ship off product to a "Legendary" member of this community, so they can evaluate it and make a post reporting on it's performance.

FWIW, I purchased and already received one unit from this vendor, it's working well, and was shipped in the original packaging. Can verify it's the older SP20 vs the newer SP20E's I got directly from SPTech.

Have three more arriving on Friday - He accepted an offer I made him at a reduced price.

For the sake of argument, the S2 and S3 are about the same volume.

It's starting to get really interesting now as the entire scheme starts to unravel...

Close to 750W, off the top of my head.

Running one of mine @ 1300GHs with fans at 20% and she's staying cool.

Here we go again... This time, scammers gonna try scamming with bad renderings of BFL Minirig-inspired images...

Echoing the sentiment of buying $100 BTC (eg: Coinbase) vs mining equipment.

The $100 you spend on mining equipment likely won't recoup its cost.

By the end of the week, I'll be retiring my lone S2 and all my S3's; only running SP20's and S5's.

Starting to feel like an end of an era...

Might you be interested in parting with two via Paypal ?

I understand the hesitation with the bad rep Paypal has with chargebacks, and I'm asking in good-faith.

I feel bad for all the people that got wrapped up in this

Read stories of some people that sunk significant monies into XPY, only to lose most everything

Very sad.

[meta] FWIW, Professionally, I've been an exclusive Mac guy since about 2004. Still a hardcore gamer today, so I have a beefy PC rig for play/VR stuff, and the latest Mac Pro and MBP 15's for work.

I appreciate stuff that "just works" which is why I switched from Windows to Mac back then to begin with - had too many problems with PC's crashing doing heavy audio work, switching back and forth between programs... but that's another story...

It's for that same reason that I'm beginning to appreciate SPTech products, and am sad to hear they are leaving the "home-miner" market, but c'est la vie...

Honestly, it's probably a coin toss if you're doing a large purchase.

The build quality of the SPTech products is higher, but the Bitmain products will probably end up being the best "bang-for-buck" option IMO, but you're likely to have more issues with the Bitmain products in my experience.

The SPTech stuff "just works" and is solid.

If I could make an analogy, SPTech would be Mac, and Bitmain would be PC.

... and splitting hairs, one could argue that the noise generated by the S5 does not make it suitable for the home-mining market without fan modifications.

Downclocked SP20's at 20% fans doing a steady 1300GHs @ ~750W and are about as loud as an S3 going full tilt (~55-60dBA)

The S5's, which do not allow manual fan control, run at ~70dBA.

Disclaimer: I have empty rooms available to me that I house loud miners in, so my "home-mining" setup might not represent the norm - Running SP20's full tilt @ ~1.6GHs

I'm honestly really looking forward to the S6, and any official water cooled solutions they have using their latest chips.

EDIT: Although I just picked up 3 more SP20's off EBay to replace all my S3's, so I have no idea where I'd put an S6 if it won't run on a 120V circuit...

I apologize if I'm coming across poorly, but I wanted to note that I take issue with the verbiage;

"Running at a max of 1.47 th/s, the prisma averages 0.8 watts per gh, making it one of the most efficient miners on the market."

Considering 0.5-0.6W is "the norm" with Bitmain and SPTech, I thought this was a little bit dishonest.

Can't go wrong with either SPTech or Bitmain for the time being. Bitmain, IMO, is priced a bit high at the moment but it's really a coin-toss between the S5 and SP20. Both are great products.

Personally, I'm favoring SPTech lately, and feel that Bitmain is starting to become hostile towards the home miner.

Having said that, I understand SPTech is not targeting the home mining market for their next gen, so, the entire mining scene is in a transition right now with Bitmain seemingly starting to go the BitFury route

My Ebay unit came in this afternoon ahead of schedule, and have been having fun underclocking and getting it running quiet. Tomorrow, I dismantle it and work on an open-air setup with multiple fans.

A thought occurred to me: At $409, shipping included via EBay, I don't think there is a better miner deal around at present (Especially with Bitmain stubbornly maintaining a $370 USD price-point on the S5's). I should probably buy another three EBay SP20's to replace all my S3's and lone S2...

Man these SP20's are solid pieces of gear.
