Hey Art, I'm not sure how old the unit is. I moved into the house 4
years ago, so it's at least that. I did do some research on the
Consumer Reports website. Unfortunately, their #3 rated model, the
Kenmore 60554, doesn't seem to be available anymore. (Fairly typical,
it seems, that CR's recommendations can't actually be bought anywhere.)
Their #8 pick, the Kenmore 6011, is available and is around $65. It's
only a 1/2 horsepower model, but we don't do a lot of heavy grinding so
perhaps it'll do the trick.
MLD, I'll give your jack trick a shot. Thanks for the advice.
