My vote is to start on a single stage. I believe that by going slow will force you to exam brass more closely, go through all the steps with more caution, and do a final exam of the finished rounds. A bit more intimate, you know what I mean??? then once you have the concept of hand loading engrained, and you know how to trouble shoot any and all issues, move up to a progressive or Lee Classic turret. This way, you still have the old faithful single stage for the odd jobs and rifle rounds. and then you have the LCT or progressive for hi output.
you could start with a progressive but what is the hurry??? and if you are trying to whiz by with high round count right away, kinda defeats the learning process a bit, right?
While every hand loader here would love to have an exotic man cave with a progressive set up in every caliber, along with tons of brass, powders, projo's, and primers, I honestly believer that at least 85 to 90 percent of us out here could get by with only a good single stage (Rockchucker, big boss II, Classic Cast, etc) and the Lee Classic Turret press. with these 2 presses, you can develop loads intimately. Once you have your pet loads, assemble quite a few very quickly.
As a side note, I have 3 Dillons, 2 Turrets, and 3 single stage and I could get by without all the presses except one, a single stage.
Good Luck Mate.
