Review on Upgraded Model BUCKTOOL BD4603 Belt Disc Sander With 4" X 36" Belt, 6" Disc, 3/4HP Direct-Drive Motor, Portable Al Base - 5.0A Power For Optimal Performance by Marco Maurer

I am super pleased so far with the quality of this sander. I bought this to replace an old Porter Cable model that died some time ago. Build quality is at least as good as the Porter Cable (if not better), with even more power to cut through moderate resistance while sanding. Installing and adjusting belts is also stupid easy. What ultimately drove me to spend just a bit more on this (vs your basic models) was the direct drive - fewer moving parts means more power delivered to the wheel/belt and fewer parts to wear out and fail. Based on my experience so far, I fully expect this sander to provide many years of solid service. Only time will tell if it proves this good over the long haul, but as of right now, I highly recommend this Bucktool sander for the money.
