If I may, .. skip the headache/hassle of single-stage or manual-index presses and pony up for a Dillon 650 w/ casefeeder.
Aside from a major increase in productivity, it's a safer design. I have literally tried to create an unsafe load (raising the ram four, five times) and been unable. It just won't double-charge. (And it's got a lifetime warranty.)
Buy the press last. Get your powder, primers, and projectiles first. You'll be surprised what a pain in the ass that is. A press is always available.
