Is there an ASIC on the market which I could order today, that would return as much or more BTC as I would have to pay for it in say under 6mths of mining? I am not sure that there is anymore.

The margins are too high, there is nothing worth buying atm. The ASIC land rush is over until the manufactures start delivering on time, and charging sensible prices.

BTC network just hit 1PH/s and no 28nm gear yet. Wait till that hits, it will be 2,3,..4PH/s in no time.
