I've mentioned this tool before - I inherited it from my father-in-law. But I'll have to run 220 to my shop to use it, and it takes up a chunk of floor space for something I would rarely use. So I've been thinking of selling it. A local man has expressed some interest, and asked about price. Is $500 a reasonable price? I've had trouble finding many to compare it to, and prices seem all over the place. This is the 3hp model.
