I have an floor stand version of this - mine is a generic model, likely from Grainger. I use mine a lot - anything from sharpening my turning tools for the lathe, to multiple sanding tasks for furniture and boxes. Mine is 9" disc and a 6x48" belt . Before I got mine, I wondered how much I'd use it - and for the type of WW I do, these tools are very useful. I have had mine for 20 years now and aside from occasionally changing belts or discs, all I have needed to do is replace the on/off switch.
But watch your local Craigslist (or other 'used tools for sale' platform), as these tools come up for sale with some regularity (as least in RDU are that is true). I have have re-posted these tools more than a few times here on NCWW. If you have time, then that's what I'd recommend. Most I see are in the $75-150 range for what I suspect is a better tool than the PC tool you linked above.
