I'd grab a Lee 2 die set (sizer and bullet seater) for 20 bucks in one of the calibers you own to get your feet wet. As a hunter I've never needed more....killed a bunch of stuff with ammo loaded on those.
If you are going to try and be a competition bench rest shooter maybe the others are worth the money but for every day shooting and hunting, I can't see it. I guess it depends on your goals and your budget but you can always upgrade later and only be out 20 bucks.
