I was in the same boat as you a few years ago. I have the RCBS rock chucker kit and could not be happier. I shopped the classified ads and found a good used tumbler and saved my pennies for quality dies. I believe I bought the best system my dollars would allow!
I also started with the ABC'S of reloading and then purchased the Lyman 49th. The RCBS kit mentioned above comes with a Speer manual with many great loads in it also. I'm a book nerd so I like to read a lot of different sources which is why I now have 4 manuals, but the ABC's and the Speer manual is more than enough to get started.
