6/24 Still looking for miners in need of repair!
Willing to take 721s that are working (last checked 1 and a half year ago I think)?
Most likely, if the price is right.

What's the magic number? Also where about are you located?
I would say, less the $100 per miner. This is assuming that it is only the miner and it's auc cable. I always look for broken units because someone might have one that is just sitting. I have the capacity to repair most miners I have worked on, unless the glue the heatsinks to the ASICs.
I am located just north of Charlotte NC USA. Could send a shipping label to you.
