Porter-Cable 371K, 2 1/2" x 14" Compact Belt Sander Kit
This Porter-Cable sander deserves mentioning partially because it is so different. This uses a 2-1/2 inch wide belt, which is only 14 inches long. That makes the sander much more compact than most, which might be an issue for some users. I will have to say that it makes finding belts a little harder, but if you need something compact, this one will do it.
The front handle comes off, making it possible to use both hands on the rubber coated curved top of the sander for excellent control. However, with cheap belts the tracking control on this sander needs constant adjustment. This problem can be eliminated by using the right type of belt.
