Roadstress,   <- (always address members in this manner as to not cause confusion. )

Please be more specific. Your question is just to broad. That's like asking Acer how many pieces of computer hardware they built and shipped. (Notice the name drop, and analogy)

We have built and shipped over 8 different models of miners to this date. With 8 different speeds from 80ghs and to 2400ghs, using three different ASIC's. Roadstress please be more specific.
