I bought a Black&Decker heavy duty one years ago for about $200-250 off one of the tool trucks.SnapOn sold the same thing with a chrome head instead of polished for 400,man they think highly of their name.Makita's are good but expensive,and I hear the Dewalt's are really good and the prices are reasonable.If you're not going to be doing alot of buffing or grinding with it you can step down to a medium duty and save some money and it should still last you a long time.Try the prices at Lowes or Home Depot,they're usually pretty good.
