Started with a Lee Turrent Press. Then I went and bought a Lee Progressive 1000, made up new swear words using it. Seemed like I was always adjusting it, and trying to get the indexing timed properly. (stupid plastic gears etc.) Finally when a primer got flipped, crushed, and detonated, causing a chain reaction up the primer tray chute, sending primers and plastic primer tray parts all over the basement, and powder burns to my forehead, I got rid of it. Went to a Dillion Square Deal next, used it for about about 15 years (about 75,000 rnds. loaded) with very few problems, just had to replace a few items due to normal wear and tear. (bushings/nylon wear bearings and a powder bar that got scored somehow) A couple years ago, I come across a used Dillion 650 with lots of extras for a good price and bought it. Been using it since, no problems. By the way, when I sold the Square Deal, I got more than I paid for it. Try that with a 15 year old Lee 1000.
I know that lots of people use the Lee 1000 seemingly with little issues, but in my case, I found that the Dillions are a lot more reliable. With the Square Deal, I was loading 400-500 rnds./hr. easily, with the 650 it is around 500-650/hr. without much effort.
