I run a Lee Loadmaster. I chose it over the Progressive 1000 because it has a 5 hole turret and not just 3. I used to run it with station 1 being a Lee universal deprimer, station 2, Lee sizer, station 3, flare and powder drop, station 4 is seating, but with the crimping spun back, and station 5 the crimp. The only thing I have changed is I now deprime off the Loadmaster. I find it keeps my press cleaner longer, which ultimately makes it run smoother, and more reliably. I now take my used brass, do a quick pre-wash with a contractors bucket with citric acid and salt. I cap it, roll it around, and let it sit for 5 minutes, roll it again, wait 5 minutes, and that gets rid of most of the dirt. I then deprime off the press, and then I run it in a wet rotary tumbler with stainless pins. This way the primer pockets are super clean, and brass is in nearly like-new condition and I keep my press clean.
I typically get less than 0.1 grain variance in my drops. It rarely goes over 0.1 grain variance. My loads tend to put me around 5 grains/round, so even at up to a 0.1 grain variance, or about 0.05 +/- intended, which means it's roughly about a 1% +/- in intended powder drop which is enough to keep me consistent in IPSC for major power factor. I have 2 go to loads now, one for "plinking", and one that makes major power factor with a little safety room. The only thing I do is adjust the dropper to a different sized cavity when switching.
With clean brass, and everything setup, I can usually crank out anywhere between 350-500 rounds/hour depending on whether I need to stop to recalibrate something or not. If all goes well, it's around 500, if I have to stop to say adjust the case feeder (I don't run a bullet feeder . . . I use that step after the flare/drop before I place the projectile onto the case as a visual check to see if the powder level seems unusual) it's more like 350/hour. The only time I have ever reloaded less than 300/hour is when I was first setting it up.
Admittedly, I did a lot of research, and information like this:

Helped to make my Loadmaster run very smoothly. I'm sure it would not run as well if I did not do the filing, sanding, smoothing, etc. Like sanding the powder drop, and smoothing the indexer rod that rotates the plate between turrets, or lubricating the grease nipples, and fine tuning the case feeder.
I have now reloaded thousands of rounds on my Loadmaster. I paid just over $200 US for it back when the exchange rate was like 0.95, and not 0.80 like it is lately, at 3% sales tax instead of 13% locally. It was about $45 more than the best price I could find on a Progressive 1000 at the time. Heck I paid almost as much for my tumbler as the press. I have now tried a Dillon 550, and it is a nice piece of equipment, but to get similarly setup with the 550 would have cost me about $750 instead of $225. Is it nicer? Sure. Could I produce more rounds? Maybe a tiny bit in terms of peak rate, but in terms of over a long trend as once you get it setup, it tends to stay that way, while the Loadmaster and I'm assuming Pro 1000 require some tuning up every 500-1000 rounds? So ya that is nice, but 3 times the price nice? Not for me I guess. Don't forget all the other stuff you'll need beyond the press like a chronograph, and highly accurate scale. Too much at stake to not use them. Would I buy another Loadmaster? Hell ya, if I ever start reloading anything else than the 1 caliber I do now, I'd get another Loadmaster without hesitation. Would I rather have a Dillon 550? Definitely. But it's not triple the price and $500 better to me. Your mileage may vary.
