depends on how much you want to spend and what you want to accomplish. last year i went to bass pro and bought a #8 LEM grinder, and the tenderizer attatchment, among other stuff. cost me $950, but when you figure it cost me 4-500 a year for processing, and i know that i'm getting my deer back and whats in it.
look up LEM, they have the equipment as well as spices and supplies.
