I agree progressive is the way to go *IF* you work it out and determine how many rounds you load and what the cost savings will be to pay for the equipment. And you need a lot of equipment.
I shoot 38 Special and 45acp for PPC League, 357 Mag for Bullseye (yes), and 9mm and 45acp for 3-gun matches. I did some cost calculations and the best for me was a Lee turret press. Starting with a full primer tray and a full hopper of powder, I can load between 150-175 rounds per hour. Before the zombie apocalypse I shot about 600 rounds for a season of Bullseye, 1200 rounds for a year of PPC, and ~1800 rounds for 3-gun. Plus practice so round up to say 5000 rounds a year or roughly 33 hours of work on the press. I can load 9mm for about $9 per 50 and 45acp for about $11.50 per 50. I've never bought factory 9mm or 45acp so not 100% how much they go for but guessing $15 per box of 9mm? Cheaper on sale (seen them for $13 or so I think). So $4 savings per box, 100 boxes, $400 per year of 9mm savings. So a Dillon system for 9mm with case feeder, bullet feeder, powder system, etc is what, $1000? So 2.5 years payback. Guess not too bad.
