You wouldn't be able to break even on them in 3 days. Maybe the very first ASIC miner did.
The difficulty is already shooting up as more and more ASIC miners come online. The only company that I know of that has them available and has started shipping them in small batches still has a backorder and a wait of 1+ months to get one if you ordered now. Another company butterfly labs hasn't even begun shipping them yet and even if you ordered one now you wouldn't receive it for 2-3 months or more. In the meantime while your waiting for one the difficulty will continue to increase from people who already have ASIC miners from ordering from the earlier batches.
There is no way to really tell what the difficulty and profitability will be 2-3 months from now. But let's pretend like you got your 60Ghash/sec ASIC miner today. You would probably be able to mine ~3.9 bitcoins a day. So lets call it $351/day. In 2-3 months the market will be flooded with ASIC miners causing the difficulty to sky rocket. Would the difficulty double, triple, or quadruple in 3 months time? Who knows. But that would knock your potential profitability down dramatically. And that is assuming bitcoins stay at ~$90 per coin.
