Where on earth are you getting that an Ant is $24 a GH/s?
It currently costs 1.45 Btc which at $650 per bitcoin is about $1000,
so 1000/180 = $5.55 GH/s
Speaking of off topic and completely FUD posts...
The $24 is for the 1.6gh version of the AntMiner (U1), since the 180gh (S1) version is/has been out of stock everywhere that sells it at 1.45 bitcoins. Again, I would love to know where to get it.
And I don't think comparing BA's offering to competitors is off topic. If people claim their products are uncompetitive, I think that is a perfectly acceptable topic for discussion on this thread.
