Here is some food for thought that you might like.. This has nothing really to do with turret vs single stage, but loading in general.
My father in law found out I bought a press and asked if I could make him some shells. I said sure if he bought the dies. Well it turns out he shoots a .308 norma and was paying $104 per 20 here in Canada.
I loaded him 8 boxes of shells for about $250 (including dies). I saved him $582 using a $99 press. Pretty cool I thought.
