.16/day? lmao...
If coins stay at current value and difficulty increases at estimated rates. You'll be loosing money by July.
time to look into your math a bit better gents
http://mining.thegenesisblock.com/These rig's turn a profit if they ship on time, anything delayed and you simply loose all money.
Minning is not a Get rich for the next year type of investment boy's

EDIT:
Going off today's value starting in March you will never make a penny off this machine. FYI.
You generate maybe 12 coins before it's into the penny coins. So you need to decide if you can buy more coins fro $6,000 than it will produce

I've pulled out of buying one of these.
.16/day is indeed extremely optimistic, but I think "never make a penny off this machine" is too grim of an outlook. The general direction of the bitcoin price has sortof been an upward trend. With more real money being pumped into the system and difficulty rising it may keep going up. Of course no one can see the future and it can just as easily go back down to under $1 tomorrow. However looking at your own estimate of 12 coins, you would break even if the price of bitcoin is $500 and you would double your investment if the price of bitcoin reaches $1000 again. To me that's pretty good odds since bitcoin is worth roughly $800 right now - which makes miners more profitable at the moment than buying bitcoins outright and hoping it will go up.
