Harley, I've been using one of these disc sanders for about two years and it's an outstanding tool. Also sold by micromark.com for about $200. They offer a nice assortment of stick-on grits.
I did find one small problem. The disc bearings were adjusted a bit too tight. When you take the abrasive off you'll see a hole in the middle of the aluminum plate. Inside there's a set screw that holds the plate and its bearings in place. I forgot exactly what I did to adjust the bearings, but it's very straight forward.
