Rockchucker was created to swage bullets, kinda says it all. I've seen where Rockchucker handle castings broke, Lee handle brkts broke, Lee alum presses sprung, Lyman and Lee C presses sprung. Haven't heard much on other stuff except Summits with upper casting issues, FA with casting and screw and dieblock issues on their fake Co-Ax. I've put a snipe on my Rockchucker a couple of times. I also like my MEC, and the Co-Ax. Not really any bad presses out there, depending on what you are doing with them. The FA fake Co-ax and the RCBS Summit are the only ones I'm aware of with persistent design/quality flaws, but will still make ammo, and anyone can get castings that check out good and turn out bad down the road.
