I had a Pro-1000 several years ago, but it just didn't like feeding 40 S&W and I didn't like seating and crimping in one step for an autoloader. For 38/357, or any revolver round using a roll crimp, I wouldn't hesitate to get another Pro-1000. The stroke is too short for most rifle rounds, and I don't like seating and crimping in one step for those either. Changing shell plates is a total pain IMO. I didn't have too much trouble with the priming system. Keep it clean. If it happens to leak powder, take steps to rectify that problem right away.
The wife bought me a Loadmaster for Christmas 2014. It came set up for 223, but I have purchased turrets and shell plates for 40 S&W, and 30 carbine and load those on the same press. So far, I am really impressed. The new Lee priming system works well, but can have issues if not properly adjusted and kept clean. An improperly prepped crimped primer pocket can ruin your session (Of course the first reloading of military brass requires of-press prep). As stated a smooth, steady pace is better than rushing. The case feeder works well for pistol rounds and the 30 carbine. Getting it to work with rifle length cases is possible, but a bit difficult.
For a single caliber, either press will work fine, but for an autoloader, I would recommend the Loadmaster. $.02
