I'm looking to upgrade my Rigid belt sander. I make furniture, and never owned a stationary belt or disc sander. Which would get more use in your shop and why?
a) Powermatic comination belt/disc sander 31A model 1791291K (http://www.powermatic.com/us/en/p/31...-230v/1791291K)
b) Powermatic 20" disc sander DS20 model 1791276 (http://www.powermatic.com/us/en/p/ds...h-230v/1791276)
