Found a pneumatic 2" sander at harborfreight tonight. Some of the others that others mention are expensive, this was $25 hook and loop pad. The sanding head does orbit around. http://www.harborfreight.com/cpi/cta...emnumber=93629 I'm going to get one of the foam pads for hook and look from CSUSA and some good sanding discs. It does seem ruggedly built. Hope that is helpful.
