IMHO you have to look at what you really want to do...and that is hard not having done it before....or really knowing where this road is going to take you....I can offer you this from my experience.
I have a lee turret and a single stage, just redid the reloading area and did not even bother mounting the single stage.
I really don't shoot that much "normal" stuff. Everything I reload for is odd ball old military calibers that are very expensive IF you can find them....some well over $2 per bang. 30-40 Krag, 7.7 Jap, 6.5 carcano, 7.5 French just to name a few. And I load pretty much all rifle on the lee turret and have had zero issues.
For all rifle stuff I don't use the "turret" part of it...it is really a 4 part single stage....one good part is it is a little like having a bunch of single stage presses....you can buy the discs pretty cheap I think around $30-ish and just leave the dies in there....it is real handy if you bounce around calibers a bit.
For me this is really the perfect press, I load at most 100 rounds at a time, and change calibers quite often, from my research this makes things like the progressive presses just not work that well, they do not just setup in a snap, and they don't like being changed around....you have to tinker with them to get everything working correctly.
I would say for the price of the lee turret press it is a great way to get your feet wet.
