I was considering that, but i'm not willing to burn my fingers when soldering tiny chips, so need assebly.
if i compare that option to bfl it seems likely as unsure as bfl delivery schedule. 1) need to turst that i get chips from group buy, 2) need to trust that PCB design works 3) need to trust that someone manages put chips on board and deliver diy boards... when? 4) and price for 50GH/s is likely same than BFL single. But still considering also diy, but not much time left...
