IMHO..........LEARN on a single stage.
IF, you are a little further along on the "experience scale and know what you're looking for" you may elect to use a turrent press. I'd leave the progressive presses until you've had time under your belt and truely knew about adjustments and what's happening at each stage/position.
Anyway, LEE sells two different "breech lock kits." One with an on press primer station (a littler cheaper then the other one) and one with the hand primer tool w/ various shell holders. I'd get the one with the hand primer cause, that is how I like to do things.
I'd also do "batch loading," to start.
Again, that's ME.
But, what you choose, is up to you.

PS.........IMHO.......
IF, you like to just make 1 or say 20 rounds or so, then head out the door, a turret press is good for that.
IF, you like to make fifty, a hundred or more at a time...........the single station and batch processing is GTG. With the breech lock "quick change".........there is not much difference from the turret press. The time you'll spend with set up........is what use to be the big factor.
But then, getting the powder measure to drop exactly what you want, is a big factor in the time spent during a caliber change over.
Thus, to get the advantage of the turret, you would want a complete set up of dies and powder measure all set and ready to go in the replaceable turret. That, can get expensive.
Also, you'll note that the single stage presses come in "kits" at a beginners price.
Most turret presses don't.
One exception, is the LEE #90928 turret press kit. But, it comes with a disk powder measure. The downside to the disk powder measure is in trying to get the weight adjustment "exactly where you want it."
With a regular hopper style powder measure, you could adjust the drop weight right where you want it.
Anyway, once you've mastered the single station and IF you still want more production then, go to the progressive.
