Personally i pass...
For that price, i wait KNCminer or Bitfury.
or blackarrow
Except that neither of those three options are available in short order, and this appears imminent here in the US.
It's exactly what i say Xian01

So maybe they can sell a lot in that "shortage" timeframe.
And it's still a better deal than Avalon Gen2 (6
BTC) or Asicminer crap
