HashFast is, most likely a scam at this point.
BFL is NOT a legit company. Would you buy from a company that promises delivery in 2 weeks but in reality takes 10+ months before shipping? I don't think so. They are NOT legit in my book. How would you feel if you bought something from a company who promised you delivery in 2 weeks and yet kept postponing and postponing for 10 months? Would you call that company "legit"?
Or from a company that offers a 25% off sale from its regular price of ~2200 only to reduce the price by another thousand after the sale is over.
BFL's sales & marketing people are evil.
