prices dropped to $7500 - still a joke.
you can get a 200GH antminer system for 3.15BTC or roughly $2200 (plus PSU cost) that uses about 1/3 the power per GH
Bitmain sets the new standard IMO. Have been very very happy with 5 of their units so far, and have another two coming in from their latest group buy.
Can't wait to see what those folks come up with next !
