A turret press is not a progressive. But you knew that so why mention it? Just to be specific, a RCBS or redding, or Lyman turret press is vastly different than the lee cast turret. With the first three, you'll have to grab the turret, turn it to the next die, to load one shell in sequence. Then there's the issue of the press being basically a "C' press. Then the turret has to have some play in the center pivot point to be able to turn. This causes miss -alignment of the dies with the ram when under pressure from sizing or seating. The lee turret is basically an "O" type press.
The lee turret can be used as a single stage/batch reloader, or with the auto index enabled, load one shell from start to finish. It has holes for 4 dies, so you can seat and crimp in separate dies with a 4 die handgun round. It also has provisions for a primer feed. Another great feature is spent primer disposal. When the primer is decapped, it falls down the hollow ram through a clear plastic hose, into whatever kind of trashcan you might have. Using the lee powder through expander for handgun, or the rifle charging die, you can use the very functional auto disc powder measure. Also the cost of the lee is less than half of what you're looking at. No. I don't work for lee. It's just that it's an option you should be aware of.
