This is my first post! Yeah! I am in the beginning stages of pouring over mind-boggling information regarding opening a coffee shop. From the looks of it, a lot of you are too! I am looking at a Bunnomatic dual commercial grinder. . . used. The owner states is has "blades." Through my research, I've only been able to find this G92 has burrs. Does anyone know if at one time it had blades? It doesn't appear to be old. I do know that I want to stick with a burr grinder and would hate to waste the money on a blade grinder for commercial purposes. Any info would be immensely helpful!!
