I got to cheat and got one of my Christmas presents early from my wife. She was sweet enough to go to Sears and get me one of the 3D Sanders that are being advertised right now. It's mostly going to do woodwork for me, but I'm thinkin' that it'd be great for body panels and other odd little nooks and crannies. Great flexibility. Grand total? ~$50. And a set of 102 varied pads is $15.
