Do you have a ballpark idea on what you're willing to pay?  With PSU's or without?

It depends on the age.  Newer ones I'd pay retail, less depending on how long they've been used.  Don't worry, even at less than retail it'd make a good, guaranteed ROI.  What do you have?

What do you consider new? I thought Bitmain hasn't made any of these since last winter?

Really?  Didn't know, thought they were batched in like s9.  We're a lot of them sold, or are they relatively rare?  Looks like 2/3 of an s9 in a flatter case.

Bitmain released several batches last fall/winter but not many as far as I know. Original batch had a higher hash rate (maybe 8.7 ths) and frequency adjustment, later batches were 8 ths auto-tune/bmminer 2.0, and later models were 7+ ths. Very cool miners, quiet, but a lot of people had issues with boards not hashing right out of the box or after few days of hashing. Bitmain Warranty in Denver fixes them for a few hundred bucks.
