Lee just contacted me. If things work out, a new press and all the equipment I have for it will be up for grabs and I will be in the market for a Dillon.
Dang... Really sorry to hear about the problems with the Lee press. I inherited Dad's old RCBS JR2 setup and used it for about ten years. Great press, reloads anything, but darn slow. I found a deal on a Dillon 550B in the local credit union bulletin about five or six years ago and I'll never go back. It is an outstanding machine that requires very little attention after you get it set up.
And their customer service is second to none. Well, maybe Glock or S&W, but I'm a little biased. I guess it's good I've had more problems with used handguns than reloading equipment.
For what it's worth, I've never seen a press mounted priming mechanism that worked reliably (i.e. without occasional headache). So far (about 5K+ rounds) this Dillon is the best I've used.
