Belt sanders may be one of those power tools that aren't pulled out often, but when you need to remove large quantities of stock, you will want to have one. The 9403, 4x24 sander is powerful, has good balance, good belt tracking and easy belt change.  This Makita also picks up a very decent amount of sanding dust, has comfortable handles, a nice soft-start, and, most importantly, chews through stock with ease. This belt sander is possibly the best 4x24 on the market. I am very, very pleased with it.
