If you do not need mas quantities or different calibers of ammo. The single stage is a great economical way to go.
One great thing about them (although it is slow and redundant) Is as you say, you can do one thing and one thing only and not really concentrate that hard.
Deprime and resize 100 or 200 cases until you are tired or had enough. You can just walk away.
Now you can take your batch of brass and hand prime while sitting on the couch or a easy chair. Put them away when done.
Now you have a bunch of primed ready to load brass,which you can do at any time when you are fresh and ready to concentrate, the previous steps was more prep or "grunt"

work, do your powder drop, check each one in the loading tray and seat and crimp the bullet. Done! You can stretch this out over time or when you feel like it. You are also looking at each piece of brass several times to be sure there is not cracks or odd looking case mouths etc.
Trying to muli task and learn a new progressive press, plus be sure every round is perfect can get intimidating at first.
No matter what press you buy, get a
GOOD scale. It is the most important piece of equipment you will buy.
