I have two kits, the one with the turret press and the one with the single-stage Challenger press.
I find that I prefer the Challenger press, as I like to do each operation one at a time. I deprime all cases, then clean them, then reprime all cases . . . etc.
I usually do just a box at a time, as I'm not into mass loading yet.
Hey, that hand primer will build-up your hand strength too! Helps ya hang onto those big bores!
For my pistol plinking loads, I just use the little scoops that come with the die set. I got the 15-piece set of powder scoops too - increases my range of loads. That was a nice accessory, though for real precision you'll need the powder measure and scale.
