Sorry but i think you've just priced yourself out of the market.

I pre-ordered in march from BFL @ ~ $25/GH
Even now their 500GH Minirig is @ ~ $50/GH

KNCMiner's Jupiter 350GH works out @ ~ $20/GH

You're essentially offering PCB design service and using Avalon Chips for ~ $125/GH

I was holding out to invest in CM3/4 but your current pricing model is way out.
