I have used the older version of the Grizzly G038 [Ryobi label at that time] for years and it has been a cheap, reliable workhorse. Obtained a Ridgid somewhere along the line but dumped it because i had a good Jet belt-disc sander.The Grizzly was easier to use, changes spindles easier and less vibration IMO. And the dust collection on the ridgid was poor by comparison. Bought a Jet benchtop spindle sander and must say it works very well but required major tuning and skirt building for dust collection. And the sleeves are expensive and more difficult to change than the cheap Griz. So if you are just needing something to occasionally smooth some curves the Grizzly G038 or Ridgid would probably workfine. I've sanded hundreds of feet of wood thick and thin with mine. But If you are thinking long term and heavy duty the more expensive units would be the way to go. Have fun sanding!
