ok sorry to chime in here with some skepticism, but the miner in the pic just looks like and ASICMINER with new heatsinks put on. sounds like someone is trying to recoup BTC from previously purchased ASICMINERS. with next gen miners out now, usb miners are never going to generate ROI.
NO ROI, unless BTC exchange rate going up 10000$... this is a tool for learning mining at home. a toy purpose.
The picture you watch carefully you'll spot the avalon logo. and later i'll post some other photos.
For ROI, ASIC on the market will never be miner-friendly. so i taped out my own design...
