I've been loading on Dillon progressives for over 20 years. First an old RL 450, and then about 12 years ago, I got the ultimate home reloader. (IMHO) The Dillon XL650.
Having said all that, I still think that you would be better off starting out with a high quality single stage press like the Redding Boss, Lyman Crusher, or RCBS Rockchucker.
Buy a copy of the Lyman reloading manual, and "The ABCs of reloading." and they will give you the knowledge you need to select equipment. The "kits" are a good idea, but often you end up buying a few little do-dads that you don't need. But, OTOH, you will have everyhing you do need.
Reloading! Try it, you'll like it!
