Looks like he's wanting at least $70 apiece for the S3s, and probably $40-50 for a PSU that'd run both of them. That'd get you about 880GH for a little over $200 shipped within the US. He's got 4x S3 and two PSUs here.
Would he split that to 100 even? for one of them ?
Yeah probably. The miners are going to be shut off at the end of the month, so if you wanted any I could ship 'em out Monday. Pretty sure I have the factory packaging from the S3s still, and they fit nicely in a box with the PSU. I shipped a bunch of S1/PSU combos last summer without any problems.
