Personally, i load all SEROUS ammo on a single stage so I can better concentrate on each step and I've been reloading for 45 years. Everyone needs a single stage. I load all my rifle ammo on a single stage, some of it on a 50 year old Pacific I inherited from my grandpa. I have an old Lyman turret press I bought back in the 70s I do much of my single stage stuff on. I've even, in the past, used the cheap little Lee hand tools. Still have one in .357 and one in .38 special. I bought a Dillon Sq D only after I got involved in IDPA in the 90s and started crankin' out lots of 9mm for practice and competition. Progressives do load a LOT in a short time, but I still have to cast bullets and that is part of the loading process and it takes time. 6 gang molds help, though, but you still have to size some of 'em. But, it's nice to set up a progressive and crank out 100 rounds in a few minutes. It takes more time setting up the press/portable bench rig than it does to actually crank out the loads. Some day, I'll be in a position to be able to just crank out 100 rounds as needed, but I have everything sort of stored right now. My Daughter needs to move her butt out of my house and take all her crap with her...sorry for the rant....and I'll be back in action. LOL I've got a small home. It can only handle so much crap. I can barely move in this place without stumpin' my toes anymore.
Anyway, you'll not dislike a single stage for many jobs and will want one anyway. Why not get it first to learn on. If you decide reloading is too much pain for you and you have better use for your time, you don't have 500 sunk into it. If you do like it and shoot mostly handguns, you'll want a progressive sooner or later, but you'll probably still have uses for the single stage press. Just sort of my thinkin' on it.
