Zeebrahed, Save up your bucks while saving money while loading for your small primer rounds and get two RL-650s! Leave one set up for small primer and the other for large.
The rest of the swap is very quick and easy if you go for the caliber conversions. Seriously, with the 650 you can load far enough into the future that you should not need to switch the primer size that often.
Should have also said that a single stage press is a very good place to learn about reloading. You will learn the basics as well as what to look for when you get those progressives humming. I am very serious here.
