I recently got into reloading. I got into it based on my volume, so I didn't even really consider a single stage press, I wanted progressive to punch out thousands of rounds I need. I now have experience setting up and running the Lee Pro 1000, Loadmaster, Dillon 550 and 1050.
Lee in general is about 1/3 to 1/4 the price of comparable progressive Dillon. Let's keep that in mind for a second. It's like comparing a Corvette to a Ferrari California. The Ferrari is roughly 3-4 times the price. Is it nicer? Sure. Is it 3-4 times better than the Vette? One's snobbery may very well determine this.
If Dillon made a press for 1/3-1/4 the price to actually compete apples to apples with a comparable progressive Lee, then we'd be talking. It's like a bunch of rich snobs saying, Corvettes are crap, only Ferraris are worth driving.
And sadly, the final product, the bullet itself is no better out of the Dillon than in a Lee. If we're talking about the final product, the bullet, its OAL, powder accuracy, priming, sizing, etc, I dare anyone to argue that a Dillon that costs 3 times more makes a better bullet, because it doesn't. You can easily make better than factory grade ammo with either Lee or Dillon.
Yes as a result the tolerances, the setup, is easier on the Dillon. Considering you set it up pretty much once, and then never again, is that worth 3-4 times the price? Basically is it worth $500-750 to make the setup easier? Because that's roughly the price difference. Do you wanna spend around $250, or $800-1000 to have an easier setup?
I read all these stories about people breaking parts on their Lee press like the ball chain for the powder dispenser. Seriously? That's the complaint?! Maybe if you didn't forcefully break it pulling on the handle when it was set up incorrectly. Honestly in cases like this, I just hope that person realizes their inability to make the press work hopefully also saved them from personal injury as lacking the ability setup a Lee probably correlates pretty well with one's ability to reload bullets safely/accurately from beginning to end.
If you're the kind of person that doesn't want to tinker, is not mechanically inclined (i.e. you don't work on your own car because you don't know how to), maybe you shouldn't be reloading regardless of the manufacturer. Buying the Dillon over the Lee because you do not have the ability to setup the Lee properly, probably means you'll have difficulty producing quality ammo on any press.
Yes if money/value had no value, than ya I'd get a Dillon over a Lee. But all those snobs that say Dillon or nothing sound a heck of a lot like snobs that look down on Corvettes, GT40s, etc because they are not Ferraris.
If you are serious about reloading, don't dismiss Lee, Dillon, Hornady, RCBS, etc. There are many more Lee presses sold, and in use than there are Dillon. There are pros and cons for both. And the setup problem is not with the press, it's with the operator.
