Since I bought 1 of these recently I was curious about upgrades for a smoother functioning machine. Although never having 1 before I have no way to compare a factory stock machine with a machine that has upgrades. So far I've seen the bearing kit for the bolt that holds down the shell plate. A roller bearing unit for the rod that rides on the case feeder mechanism. Case feeder (which I really want). And spent primer upgrade which seems nicer than the factory supplied little bin. And last a roller handle that will be the first thing to get.
Am I missing anything else?
