I don't have a lathe and I no longer cut the grass, so I don't really need to sharpen anything.
It would be nice to have a bench grinder that I could stick a wire wheel or polishing wheel on if I needed one.


What should I look for?
Variable speed?
6" or 8"?

Wen, Baur (Harbor Freight), DeWalt all have similar models - except the DeWalt is a single speed and the reviews of it are pretty bad on the DeWalt site.

I'd like to stay under $150.
