Need some insight. I am looking to purchase a sanding machine for my shop. I first started looking at just the 12" disc units then got to looking at the belt/disc combo units and now someone had said in one post that an oscillating edge sander would be of more use in the shop. Anyone got some suggestions. I will be using the sander for many tasks not just for pens. One more question though. Do you guys who have the jet 12" disc sander find the miter slot that goes straight at the disc of any use? Thanks.
