I can tolerate it. I keep spares of the plastic gears and cams. I have set one Lee 1000 up to do .45ACP and I don't change it. It stays in .45 with adjustments for different bullets or powder changes being the only planned changes to the configuration. Even so, it is not without it's quirks. It was old when I got it and came to me in pieces in a box.
The biggest issue, the ongoing issue, is feeding primers. If I ever get it where it just feeds primers, doesn't tip them over, tip them sideways, fail to feed them, or jam them up under the shellplate, I will be able to double my production rate. I read the tips in the forums, I watch the videos on YouTube, I keep it clean, I keep it lubed. What I mostly do is load at a slow deliberate pace, and as I see the next case go by the plastic tab that releases the next primer, I pause, seeing the primers move in the feeder before I complete the cycle.
Ideas are welcome. Suggesting that I splash the press off a pier and buy a Dillon is an idea. Paying for a Dillon is another idea. Let's pretend I am keeping the Lee for sentimental reasons and would just like it to feed primers. Any of you have a Lee 1000? That you use regularly? Does it just feed primers and give you no problems?
Here's an interesting video. One of the things I liked was when he turned the camera to show one of the mods and you can see the cases of food he has stored in the background.
