I am fairly new (2 years) and only load pistol. I'd suggest starting with the cheapest single stage you can get. For three reasons: 1) You may decide you're not really into reloading and 2) You'll have to reload a BUTTLOAD of 9mm to amortize the cost of your gear and 3) single stage loading teaches you intimately the steps involved in reloading and forces you to pay attention.
My story. I was shooting 9mm and buying ammo at Walmart. 9mm Federal was (pre-craziness) cheap and affordable. I saved all my brass for no particular reason. I shoot weekly in an informal IDPA style club. 100 rounds a week or so.
One day at a match a gunsmith/dealer buddy brought a 1911 he had for sale. Brand new in the box 2003 Smith and Wesson billboard. This was 3 years ago. He disassembled, cleaned and lubed it and I was the first to shoot it. Love at first sight. I did better in the match that day shooting a 1911 for the very first time than I had ever shot with my Sig 9mm. I wrote a check on the spot.
On the way home I realized, holy **** a hundred rounds of .45 a week is going to break me. I'm going to have to learn to reload.
Told my buddies and at the next match they brought me a Lee single stage, dies, scale, tumbler, manuals EVERYTHING I needed and said "keep this stuff all summer, we'll teach you to reload on it, if you discover you like it, buy your own setup cause we're gonna want it all back when you're done". These are fellows who ALL have elaborate Dillon rigs.
I eventually replaced the single stage with a Lee Turret press, a step between single stage and progressive, but I use it mainly as a convenient way to keep dies set up for 9mm and .45 and do most everything in what amounts to single stage. I paid less than 300 bucks for an entire setup including 4 die sets for both calibers, auto prime, powder dropper, scale, everything. I load about 200 rounds a week and figure on .45 alone that setup paid for itself in no time.
YMMV but that's my 2 cents worth.
