It is kind of scaring me that the March batch of Antminer A3's are not sold out yet.  Why are people not buying these when the Return on the Investment is soo much higher than any of the other miners being sold.  Using the mining calculator you supposedly can be in profit after 30 days or less.  I hope when the March orders come in that will still be the case or at least somewhere close to that vicinity.  I guess we will see.
