I actually prefer a single-stage press, but I am old school...as I still use a balance scale and hand weigh each charge and do most my brass prep by hand. I have 2 old CH single stage presses and love them...they are stronger in my opinion than the RCBS rockchucker...but I will say the rockchucker is a good beginner press. The Hornady Lock-n-load presses also get good reviews, my brother loves his! I use RCBS dies mostly and am happy with them.
Basically you need dies, a press, tumbler, powder measure, case deburring tool, powder, primers, brass and lead...and a good reloading book! I like the Nosler, Hornady and Speer books...all for different reasons. Reloading is a disease and eventually you'll need a whole room dedicated to it and more tools than carter has pills! Buy a book or two and read up a little before you buy tools...Enjoy!
