I would really recommend a single stage to start out with. I got the rockchucker about a year ago, and while it does not set any speed records, I think that is a good thing for new reloaders. With the single stage press you actually learn the fundamentals of each process, rather than just pulling the handle and making a bullet that may or may not have problems. Speed should never be your primary concern when it comes to reloading, especially if it is something you are new at.
You can buy a rock chucker kit, which includes the press, powder thrower, scale, lube kit, & loading block for about $300 bucks. Everything but the press/ powder thrower can be reused when you are proficient enough to upgrade to a progressive press. You also always have the option of selling your single stage equipment when you upgrade, offsetting the cost. Or you could just keep it around for rifle calibers you may want to load on a progressive press because you only shoot 50 rounds a year.
My opinion is that you need to learn what each step of reloading is about before you worry about speed.
I have probably reloaded 5 or 6 thousand rounds this year ranging from 9mm to .223. Once I load another 3 or 4 thousand rounds, I might upgrade to a dillon 550. But, I still feel like there is more I need to know before I get away from single stage reloading.
Either way you decide to go, just be aware that you will become more addicted to shooting and everything gun related because of it.
When you shoot factory ammo you just shoot and then go home. When you reload you shoot, pick up your brass, clean your brass, then reload it. All the while worrying about which powder, which primer, which bullet, which seating depth etc. You worry about velocity, pressure, etc. Despite all this it makes shooting better because you are much more in tune with what you are doing.
Also, buying reloading components becomes more of a fetish for a lot of guys than buying guns. There is just something about seeing 50 lbs of gun powder, or 15000 primers sitting in the cabinet that just makes me happy, and you will probably find the same thing true for you.
Good luck, and welcome to the addiction
