Bitcoin Miner Profit using 600 GH/s Monarch from Butterflylabs Butterflylabs has a new 600 GH/s Bitcoin miner for $2,196.  

According to here, 600 GH/s at today's rate would mine approximately $170 a day. This means you make back the original cost of the miner in about two weeks and start making a profit from there on.

This seems too good to be true. Is there something I am missing here?
The part you are missing is that it is a preorder and the current estimate is that if you ordered now, you would likely not receive your mining hardware until April 2014.

This site shows a good calculator and I have configured it to show the (lack of) profits you would make if you started mining with this miner starting in April:
