user1498: https://en.bitcoin.it/wiki/Mining_hardware_comparison says that it's $599 and can do 80GHz per second.
Okay, it's not sold anymore at butterfly labs.

user516: Actually, the table you linked to says it can do 832 Mhash/s and uses 80 Watts of power.
That model is no longer offered by BFL because it used FPGA technology. That technology has now been superseded by ASIC technology which is many times more efficient. 
This is probably the more recent equivalent product, which provides 30 Ghash/s for $649 (ie 36 times the output for a price 8% higher).
