Consider a turret type press. You can set up the dies and the just chance the whole plate when you change cartridges. Saves a lot of setup time.
Plus it's a lot faster than a single stage 'Rock Chucker' type. If you're loading rifle cartridges, make sure it'll auto-index correctly. My Lee press isn't tall enough to clear the case from the dies before the turret begins to rotate. It works fine for pistol ammo or if you want to index by hand.
