Hey snakeman, I bought a rockchucker as my first press. It is a really good single stage press. But, it is really slow. After 6 months I bought a Dillon 550B progressive press which I believe is the best progressive press on the market. I got the 550B because I figured (correctly) that I might be reloading rifle one day ( about 60 days later)
If I were to start all over knowing what I know now I would get a 550B (rather than a Square Deal B) to give me the flexability to do it all. If money is a problem, a used Dillon is a better deal than a new single stage of any manufacture.
Hope this helps, Mikey.
