I'm not even sure what these things are properly called. They are a rather miniature belt sander with sanding belts about 3/8" wide and are hand held. The belt, belt support, and I suppose nose roller (if it has one) extend about 6" out past the body, and are used for finishing in hard to reach areas. The ones I have seen are pneumatic, but I'm sure there must be electric ones available. I have seen prices on the net ranging from lows of $70 to highs of $400 plus. I would like to buy one that is electric not pneumatic, in about the $100 range. Does anyone know of such a device and where it might be found/purchased. I have checked BusyBee Tools, Princess Auto, LittleMachineShop, and Canadian Tire with no success.---Brian
