Ok, I've been haunting the pawn shops looking at small belt sanders. There seem to be two basic types, one with a horizontal 4 inch belt and vertical disc, and one with a 1 inch vertical belt and disc. I don't grind my own blades (yet) so dont think I need to spring for a Burr King right now, but for finishing handles, polishing ect. which of these seems to work best, and what are the drawbacks of each.
