I've been using a Pro1000 to reload 223 for High Power shooting ammo. Well over 3k rounds have been cycled through the press. I "downgraded" the Lee autocharge to spring return, that way the only thing I do on the upstroke is seat primers, I get a much better feel that way.
My take? I think the Pro1000 is a tad finicky, but when you get it adjusted it works ok. If you don't like to tinker look for something else.
Only 3 stations, so you are a bit more limited in your die sets. The Lee LoadMaster is not much more and it gives you two more stations.
If I had to do it all over again I would have started off with the Loadmaster for rifle cartridges. For pistol cartridges I think the Pro1000 is adequate.
Machine guns are awesome until you have to carry one.
