I had a Hornady LnL and it was always needing something adjusted and didn't have sufficient leverage to adequately prime cases in my example. Hornady could never make it right. I still use the powder measure though.
I sold that and moved to a Dillon XL 650 and it's been mostly trouble free. There are annoying little stoppages infrequently, but usually a new part here or there or a decent cleaning will fix things up. Fairly easy to do >700/hr. as long as I have primer tubes pre-loaded, but I also have a bullet feeder which helps.
I know I wouldn't go back to Hornady and it's about the only thing in the same price bracket as a 550/650/750 with similar production rates, so I think I'd be inclined to look at something like the 10-station X-10 Frankford Arsenal press that's supposedly coming out "soon".
