I'm going to buy a slow speed grinder. Any recomendations?

How's the new one from Garrett Wade that runs at 1120 RPM? The
"Ultra-slow 1120 Rpm Vertical Grinder"
http://www.garrettwade.com/jump.jsp?...emType=PRODUCT

Is 1120 RPM a big advantage over 1700-1800 or is it a "who cares?"

Sure would be nice to have a variable speed grinder -- are there any?
