I found this company that makes 20" Disc Grinders and other stuff while looking around online. I didn't read much on it so I don't know if it's an import or not, but at $795 bucks it's a steal. I paid $1500 NOT including tax and shipping for my 20" USA made Conquest Disc Grinder. It sure looks like a very nice grinder. My 20" is probably one of the MOST used tool in my garage for fabrication. It says it's a steel disc, My Conquest is Aluminum. Steel is better, more Mass for Cintrifucal force for cutting/grinding.
