Is the 650 really worth more money for a hobbyist to use? Sure, it's faster and has auto-index and a couple other things, but the accessories are far more expensive, and the price difference between the 550 and 650 is about $130. A friend and I want to go in halfs on a reloading setup, we want to load stuff from .308 to .38 S&W. We're not going to be loading 1000 round lots, but we'll probably be doing 100 rounds at a time. That being the case, is the 650 really worth the extra scratch, or not?
