^^ Since we're rapidly approaching the "point-of-no-ROI", there's little interest in investing several thousand USD's on half-a-miner. However, if you were to release a smaller device based on 2 of your module PCBs, giving us a much more affordable ~5.4GH/s device, there would probably be a higher interest. The additional effort for such a device would be minimal, and DIY guys could always expand upon it, using the same controller module.
^^ I think interest has been gauged already!

any other batch! .
