I've been looking for a used quality bench grinder and finally found one on Craigslist I could afford - $150. It's missing a few parts but nothing I can't make and they don't affect its function. Got it home and wired, and it is fantastic! No vibration and quiet. It has a coarse cone-shaped grinding wheel on one side and a buffing wheel on the other, so I'll need to get my hands on new wheels as I dive into grinding HSS lathe tools for my SB 9".
