got mine at BTC.107 per and they run at 70khs. Also they hash out in BTC only mode as fast as an antminer U1. For four of these it is cheaper than building a whole rig. And it is portable and way cheaper on power. When the price comes down, and it will, those who went all in on GPU for scrypt will be wondering what happened. These will eventually cause difficulty to skyrocket and a new algorithm will need to be developed, sound familiar?
The antminer U1 is 1.6Gh/s and OC easily to 2, the dual miner is only advertised at 500Mh/s what are you getting?
running in BTC only mode it hashes the same as the antminer u1
dual mode is 500Mh/s sha-256 40kh/s scrypt
scrypt only is 70kh/s
