What kind of quantities will you be loading. If only a couple hundred per sitting, the turret. If a thousand or more, the progressive. If in between, you will just have to figure out what suits you. Tglzie has good advice.
I myself used to have a couple of used Pro-1000 presses that I retired in favor of the Lee Clasic Turret. I never got comfortable with monitoring multiple simultaneous operations on the Lee Progressive. My style is much more suited to the turret and using the auto-indexing that allows continuous (vs batch) processing, my throughput on the turret is equal to my Pro-1000's and I am relaxed at the end of it.
But tha't just me.
