I fully second, third, or forth (whatever the count is up to at this point) the Lee Classic four hole turret press.

The only other one I would look at is the Dillon BL 550 that will do the same thing for more money, but has the bonus of being buildable into the RL 550B down the road.

And before you buy anything, buy and read two or three times the "ABC's of Reloading" now in its 9th edition. And read it over again. And again.

And again.
