Brewpub is right, it takes a long time to recoup the cost of equipment when reloading. It's a hobby you do for fun or accuracy but cost isn't one of them. My single stage set-up cost somewhere in the neighborhood of $600, not including brass, primers, powder, and bullets. Add in whatever you think your time is worth and it'll take a couple years of reloading just to break even.
Yes you can get into it for about $300 but it's all going to be Lee stuff that you'll eventually upgrade from.
