IMHO that is enormous price if it were true. I was hoping $1/Mh was the maximum price point. Guess not ...
The FPGA alone is going to be $150 ea. So @ 180MH just the FGPA is $0.83 per MH. Kinda unlikely that everything else including PCB, minor components, USB interface, assembly, and retail markup are <$0.17 per MH.
