Hello The factory was never able to keep up with demand In their hey day, and then other people started making progressive presses. I have been loading on mine for over 30 years and you can change calibers in 5 minutes if you have an extra set up tool head. I think they are better then any other press as all parts are steel with the exception of the brass parts that store/ move the primers /powder as brass is none sparking. The dillon is a "copy of some of the star idea's and at one time there was talk of a law suit dillion has great customer service but their presses break parts more often . and are IMHO they are larger then needed if you are just loading pistols. There are a number of places to buy parts and I buy and sell setup machines for bullseye shooters.
