Ben would be correct regarding spare parts. I have one in 38 special, I picked it up out of my friends trash, he darn near had a nervous break down trying to set it up, finally canned it in frustration. You will definitely need the owners manual to do the setup, it is not like any press you have experienced. I don't use mine to prime, I've always did that as a separate step, regardless of the press, so I always avoid the jammed primer hassles. Part occasionally show up on Ebay, if your patient, they eventually show up. The powder measure is a Little Dandy with a actuating disc screwed to the back of the rotor. I really like mine, I setup for wadcutters and three grains of BE and haven't had to make any adjustment since and I have pounded out thousands of rounds. If you could get one for little money, complete. I'd say go ahead and do it. Short of that, there are a lot better choices to be had in progressive reloader. Just my opinion FWIW.
