Myself, I would have that Rockwell than lot of new DP's. No longer made but if it works now it will work from now on unless its been drop or beat to death. Rockwell during its prime sold lot of Rockwell equipment to professionals, hobbyist, and school district which is where I work at. Lot people will say replace the bearing, but I think that is said just make new owner fe el good. If it runs smooth or if there is noise check see if its the motor or not. Over the yrs I have gone through Rockwells table saws, several of their bandsaws, belt sanders but never really did a DP but there is not much to them. So if price is right and it runs as it should then thats a good find. Or if your into restoration projects that will be good one.
