The square deal is a good little pistol setup, parts do wear out quicker, and Dillon is happy to replace them, I would lean more toward a 550 - 650. The 650 does take a little more learning curve to get started. As slickrob mentioned, you can get carried away on a progressive and forget to feed it. Dillon does sell a powder and primer monitor that beeps whenever you start running low. Make sure you get the video from Dillon, I believe it's free with a press purchase and will help you out quick. When I started reloading, no one I knew did it. Believe me, I did a bunch of stuff wrong or the hardest way. Met a guy at my local public range, who lived pretty close, and we had loading parties, We all had single stage presses then, and We would put 3 presses to work and a lee auto prime and load 600,700 rounds in one night with 4 guys doing separate operations. Your square deal or a 550 will do that with just you in 2 hours, 3 if your just taking it easy.
Best of luck.
