There are better deal out there, even if this other hardware consumes more electricity. 11 btc for 280 GH? Why in the hell would I do that when I can get a Jupiter for just a few coins more and get 550 to 650?!
These are in stock, most likely ready to ship. Jupiters are not.
The only other ASIC hardware that's available at a reasonable price is the Antminer, but they have been forum/auction style sales only so far.
