Anyone have any suggestions on a decent light industrial grinder. One that can run continuously for a few hours every other day, without heating up your coffee. Only thing I could find online, that fits the bill, is MPE Chicago's GPX line. I'm guessing these bad boys aren't cheap. Going to call then direct to find out. I did see a dealer selling them for $7,500. Any other options out there that won't break the bank? I have 2 commercial BUNN G9 grinders that are great but I don't to burn them out. This client wants 500 ground coffee pouches per week.
