My faithful PowerSpec 3D Pro dual-extruder printer died, and I'm casting about for repair options. I suspect the power supply died, but I haven't yet torn it down to see.A year or so ago I remember there were a bunch of PowerSpec 3D PRO printers being sold for parts. They were represented as 'non-functional', but I heard lots of reports that what was actually received was a working printer with maybe a few cosmetic dings.I searched around for anything on the net, but couldn't find any references to that source. Any additional information or pointers would be appreciated.TIA,Frank
