I was in the same boat awhile back. I went with a hornady lock n load progressive, mainly because that's what some others I shoot with use and I was new to reloading. I've been loading .40 and once it's set up its a breeze.
I can load about 250/hour taking my time, and I'm pretty new to the reloading game so I tend to be careful. I'm sure you could do more if you wanted to. I don't have any experience with other presses, just thought I'd give my experience on what I have.
In the end I think it comes down to how much time you want to spend reloading. A higher end press will allow you to pump out more rds/hour. For me I'm pretty satisfied with a rate of 250/hour. Also I think I'm going to end up liking the lock n load feature as I look into doing other calibers.
