A Dillon 650 is a high-volume progressive press; most folks do not recommend something like that for a brand new reloader, but if you have the aptitude and hopefully someone to show you how to tweak it as necessary, it is a good machine with good customer service.

Don't know what your definition of "a lot" is, but if it isn't in the high 100s or 1000s per month, the 650 might be more expensive than necessary to start.
