There is a lot of old bench grinders out there that are great but they don't make them any more. If you are buying new a Baldor is the only one to buy.
Actually my bench grinder is a Baldor that was sold by J.C. Penney and the tag on it says J.C. Penney, paid $35 for it 35 years ago, What a deal.
I bought a $25 el cheapo about 19/20 yrs ago, it s not the strongest and far from the best, but it`s still ticking, a real pain in the *** to change stones and brushes on---------
