Bitmain is the only choice for Bitcoin Mining
Why do I say this?
I have purchased 267 Antminer S1's. Out of 267 S1's I have had 1 problem unit. One unit with a dead ASIC blade. That's it, 99.8% success rate. That's unbelievable. They just keep running, and running smoothly.
I have purchased 27 Antminer S2's . Out of those 27 S2's I have 1 blade that only half worked (From batch 1. The heatsink had a burr on it that cut into the board and shorted out half the blade). I also had 1 power supply that melted as the cables weren't connected tight at factory. While batch 1 had a good amount of extremely irritating issues, batch 2 was much better and batch 3 was nearly flawless (A few loose internal cables). I have been in contact with Bitmain concerning all the issues and they are indeed working to correct where they have come up short.
I have no doubt the S2 will soon be just as rock solid as the S1, and as you can see form above, the S1 is gold standard in ASIC hardware.

That is crazy. Are you still mining with all 77TH? Do you personally own all 77TH or is this hardware shared as part of a mining group?
I have 20 S1s mining right now, and all work flawlessly, so I hope Bitmain addresses the S2 quality issues and offers a new competitively priced batch of S2s soon.
Bitmain not only offers a great product at a fair price, but they are also putting an end to a lot of the shenanigans pulled by other hardware manufactures by forcing them to alter behavior in order to stay competitive.
Just say no to pre-orders!
