Ever consider a turret? You don't have to change dies, but you're in complete control of the process. I'm not trying to steer you away from a Dillon, but until you really know what is happening with each stage, what adjustments to make, etc., it may be a little overkill to go with a progressive.
Lyman & Redding make great turret presses. You can buy a different turret head for each caliber, and maintain your die settings.
