I'll have to agree with kaferhaus. I reload for the various subguns I own with a Lee Loadmaster which is going on 13yrs old and still loading as well now as it ever has. The vast majority of my reloading with this machine is 9mm, but I also load other various pistol calibers. Conservatively, I have loaded 50-60k rounds with this machine. Not a fanatic, just a guy with 1st hand experience, not parroting an old song.
Yes I have replaced a few of the plastic pieces due to wear or getting deformed in the process. Therefore I keep spares for this infrequent occurance. Replacement of the small inexpensive pieces happens WAY less frequently than a lot of people would lead you to believe, but replacement is a snap nonetheless. I have no experience with the Pro1000, but for me the LoadMaster has been a solid quality machine. I also understand how the machine works, and therefore setup, adjusting or tuning for proper function is not a problem. The thing I find most difficult with the LoadMaster is making sure I keep an eye on my primers (and powder) not to run out once I get into that "3 case rhythm."
I haven't priced machines lately, but the last time I bothered to look, one could buy 3 LoadMasters for the price of one of the blue machines offering the same features.........auto index, case feed etc. I am not putting down the blue machines as I'm sure they are great. In my experience, and for my purposes, the LoadMaster offers way more for the money. If you're going to reload pistol caliber, the LoadMaster should more than fill your needs. As simple as the LoadMaster is built and operates, do as kaferhaus suggests and also read the manual.
