Was out working on the truck radiator support rebuild this morning and the grinder died. The brushes were shot and I stuck in the spare set. They lasted about 10 seconds and were toast so I'm looking for a new grinder. I can get the same grinder(Kawasaki 4.2a) for $29.99. Since this grinder lasted 2 years under what I'd call light use, I'm thinking of getting something a bit stronger. I'm considering the Dewalt DWE4011(7amp) for $59.00, the Hitachi G12SR3(6amp) for $49.97, the Dewalt D28110L Q(7amp) for $59.97, the Bosch 1380SLIM-K(7.5amps) for $66.97 and 1375A(6amp) for $69.00. I normally would get one of the Bosches but I need this now and I can't get either of those for 2 weeks.
