Each round takes a different die set ($20-30). In rifle that's usually a 2die set that consists of a sizer/deprimer and a 2nd seater die. Pistol die sets are in 3's with a decapper, sizer and seater. On top of that you will need a lot of small things that doesn't cost much (debur/chamfer tool, primer pocket brush, etc....).
If you don't want to do this as a hobby then it's not worth it because if you go into it thinking only about money then it won't be worth it.
To me it's #1 a hobby and #2 a money saving way of getting ammo.
I load .40 , .223 and 7mm mag on my RCBS rock chucker2 that I got off craigslist. With it I got a powder measure, trim pro brass trimmer and 505 scale all in RCBS. I got it all for $200. I've added a lot of little stuff to it to make things easier but i don't look at it as money saving but a hobby.
I load 40 at .18 a rnd, 223 at .22 a rnd and 7mm mag at .35 a rnd and that's all on a single stage. Any newbie should start on a single stage and not even look at the rounds per hr of the progressive presses.
I've been loading for a few years on my own (learned when I was 10 with my dad) and I'm just ready to invest in a progressive now.

Don't let it get you down and keep doing your homework.
I researched for a couple months before I pulled the trigger and am glad I went with RCBS.
Their customer service is amazing as they don't ask questions and just send you the parts free of charge. Lee won't do that.
