Thats not really a good deal considering you can get new U2s for about that price.... Tell You what I will offer .08 for all of them...
The only difference between the U1 and U2 is the heatsink. I think they also installed the resistors as well. I've got the resistors, but I haven't soldered them on yet. Definitely need to do better than .08 BTC... I'd rather trade them for some scrypt asics...
