I concur with the opinions of "Unclenick" and "Jim Watson." If you're brand new, it makes more sense to start with a single stage press, or at most one that can be switched to single stage, like the Lee Classic Turret. The cost is far less than a Dillon 550 ($80 at Midway), and you will use such a press for a variety of tasks, even after you've gone progressive. I would also endorse backing up one stage, and first getting one (or several) manuals, and reading them until you understand each stage of the reloading process. People have their favorite manuals, but I think any of the major publications will explain the process adequately: ABCs of Reloading, Speer, Lee, Lyman, Hornady.
