They are the best or second best  in terms of you will get working gear.

Bitmaintech

Avalon or Cannan

Bitfury is on the list  but you need heavy money and must buy big.



At this moment in time  only choice from above is bitmaintech  since they are the only one selling gear.


I currently have 6000 usd in orders with bitmaintech.

and if Avalon / cannan had new gear for sale I would buy 6000 from them.

Bitfury has no new gear and I would not have enough money to buy from them.

So if you want to buy today you only have bitmaintech to buy from.

The big problem they have over the years is if your gear breaks they are poor at helping you get it going again.
The good is they get it on time most of the time.
They gear works most of the time.

So if you buy 6000usd  like I did I know that it is more like 6200-6400 in terms of real price due to slow repair risk.

With 3 pieces for 6000 I am hoping they are all good and the premium of 200-400  does not come into play.
I have order 40k in gear from them  more then 50 items since dec 2013.  every item was delivered most on time or early a few late.

1 item was doa  and it was a struggle to get repairs.
1 item was a very poor performer and its was a struggle to get a partial refund.

in both cases i did get  my repair/replacement >>> about a week but a large miner did the replacement not bitmaintech ,bitmaintech would have been 1 month

 and my partial refund >>took about 6 or 7 months

So I rate bitmaintech better then okay to buy gear from.
