An early post stated that what you plan to load, and especially the volume, will determine which press (or at least drastically narrow it down) you buy. I agree with this. I own two Lee Pro 1000 progressives, and they work fine, for the pistol calibers I load on them, and in the quantities I shoot. I don't anticipate wearing them out. However, if you're loading ammo in the quantities necessary for competition/practice in many of today's high-volume courses of fire, say a couple of thousand rounds a month, I wouldn't consider a press like the Lee. I believe you'd wear it out in a few years.
I also own a Dillon XL650 that I've had for a few years, and I think very highly of it, and use it to load both pistol and bottleneck rifle ammo. It produces very high quality ammunition, and I have had none of the problems with the powder measure or primer feed that I've read about in various forums. I should also mention, however, that the Dillon is "too much press" for the volume I shoot.
Whatever you do, don't get caught up in the "color religion" that seems so pervasive when it comes to progressive presses. I think all the major brands out there, from what I've read, will do the job, and if you're having problems, their customer service will help you get back on track. The service is as important as anything else; I've called customer service at Dillon, Lee, Lyman, Mec, and RCBS for one thing or another over going on forty years of reloading, and have always received prompt, courteous, and efficient service.
