I seem to remember a couple of days ago, someone recommended an inexpensive Sears belt grinder to start with. I looked in the catalog and found three. Since the catalogs are at my son's house I don't have them in front of me and can't remember which grinder was recommended. Is anyone familiar with Sears belt grinders and can you give me the particulars on which is the best. I remember there was one each for about $190, $120, and less than $100. Thanks in advance.
