It's got to be a spindle sander with 1/2 hp and "extra drums". Most drum sanders have much bigger motors. I have been looking for a oscillating spindle sander for quite awhile. I don't really "need" one so am waiting for the right one at the right price. Now if that was a floor model Griz, General, Delta, etc. it would be a good deal. Not so good if a bench model.
Sent him an email, so will see what the deal is.
