I have a few "SOMETIMES" working R-Box 32-37 Gh/s miners and a Antminer U3 just sitting around bc I couldnt get it connected if you're interested.
Holding on to a Avalon 4.1 that still runs at 950 Gh/s that I may part with if you wanted one. Just re read the thread and don't think this fits your criteria!
I can't use the R-box stuff. I actually would be interested in the Avalon. PM of post here with what you are asking.
