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.
