It serves a niche as you said. I own 2 Lee presses. The Classic Turret which I started on and keep around for non-high volume calibers. I also own a Load master. The Load master requires tinkering to make it work right and I fight sporadic flipped primers and no primers. It works great for the 250 bucks I have in it. I have loaded several thousand rounds of 9 mm on it for competition. Have learned its personality. Clean it every so often(every 500-1000 rounds I tear it down and clean debris out of it). Every once in a while, it starts acting up. I have learned the feel for when a primer goes in right. I am seriously considering, if I don't go Dillon, doing the camera trick someone posted about a couple weeks ago.
The guy that got 8 sets of defective dies. I'd venture to guess he was very picky on the dies and they couldn't make him happy if they gave him the dies.
Back to the Lee Presses. I have determined that if you don't like to tinker with your stuff and just want it to work....that's why people go to other brands. I don't mind tinkering, but am considering stepping up to Dillon 650 just because I can a) afford it if I want and b) I would like something that I can reload quicker on. Whether I actually do it anytime soon is a question. The Loadmaster is working fine for me...just not as fine as I'd probably like for high volume reloading.
Lee is gonna set you back 250-275 for a Loadmaster. On the Dillon, for the same setup, it would cost you 900(give or take 50). That's a press and case feeder. Is it worth over 3X the cash...we will see...but I'm sure after I get over the sticker shock I will be happy with it.
