I have a Jet 6-Inch/12-Inch Belt/Disc sander that has been in my shop for quite a while and has not been used much. I am thinking about selling it and getting a drum sander - either a 16x32 or a 22x44. Which is more useful for the hobbyist, the Belt/Disc or the Drum? With limited floor space I can probably only fit one or the other.
