I bought one a few years ago. It worked great for awhile. Then, I started getting run out on my rounds. I noticed the ram had play in it. I reordered a new frame, ram and linkage from Lee ( one of my dumber moments).
Again it worked great for awhile, then the runout came. My guess is that the aluminum frame is not the best choice for wear.
I am now the proud owner of a Forster Co-ax press
