For guys that are on a budget like me, Lee Pro 1000 is the only economical way to go. You can drive a civic and it get you from point A to point B and you can drive a BMW and it get you there a bit faster. I think the problem with those who have owned Lee Pro 1000 and hated them is because they do NOT understand how the press works, they just want something that work all the time without having to maintain them. And that's perfectly understandable(is that a word?) Anyway, the point is, go over the manual carefully, watch the video on the Lee precision website. And carefully look at the design of the press and UNDERSTAND how it works. And once you do, you will know exactly what to do when something goes wrong. Primer feed is the main headach causing design. The proper feeding of the primers depend on the weight of the other primer to push on it so that it slides proper into place. So when the primer feed is dirty, the primers get hung up in it, and there's no weight pushing on the primers at the bottom, of course it's not going to load properly. So? KEEP IT CLEAN, and keep the primer tray at 1/4, AND I would highly recommend CCI primers because it's nickle coated, they slide better than the Winchester copper ones.
And what happens when you miss a primer and get powder all over the place? Get a can of compressed air to blow all the powder out, or if you have it setup in your bedroom(like me, I'm renting an apartment ok? so stop laughing) Use a handheld vaccum cleaner to suck the powder out from underneath the shellplate and carrier assembly. If there's a primer jammed in the priming station, just use a little pick or something to flip it out, it may or may not be reusable.
If you are really not paying attention and have loaded 100 rounds with no primers on them and got powder deep into the shellplate carrier and the whole thing just stopped working. Then you gotta take the press apart. I'm not gonna go over how to take it apart, it's all on the manual. If you don't have one because you got it 2nd hand, get it printed off from lee's website. There aren't that many parts on the press it. It works on very simple principles, understand it and work with it, develop a feel for it. And you'd be just fine with it.
I've had priming problems, case feed problems, and had to take it apart when I just started loading. But after a couple of times of taking it apart and putting it back together, I understood how it works and haven't had problem since then.
