I myself am new to reloading but I did go with a Dillon 650, it was a tossup between that and the Hornady L-n-L and final decision was based who was close to me that can help me through my learning. I don't think you can go wrong with either of the 2 machines I mentioned. That is if you are willing to lay out some coin for a progressive.
One thing that was mentioned, was a single stage, and I will still get a single stage for some rifle down the line so I can keep the caliber changes to a minimum on the progressive, plus as many people have been loading for some time will tell new people, you will learn more on a single stage, that and it will always have a place in a reloading setup anyway.
Another thing to do even before you get a press, pick up the latest additions of the Lyman's, Speer, ABC's and any other book you can pick up. While the web is great, you can never have too many hard copy manuals for reference.
