When I started my project almost three years ago I bought a DA sander at HF for $20. It has worked very well for me over the years as have other things purchased there. During that time I have been through about 3 of their cheap 4.5" grinders but they do the job and for $18 on sale it will take another two of these cheapies to cover the cost of a name brand grinder that probably would have worn out itself during this time.
