First off you want to get a book like the ABC's of reloading and read it cover to cover, then read it again. Then research some more on presses, dies and accesories ect.
A lot of people bash lee but thats what I started with and have no regrets at all. There stuff might not be as rugged as some of the others, but like Richard Lee states in his reloading book, they don't overbuild things. They use enough materials to get the job done and hold up to the stresses of reloading. They were not building a press to put rivets in truck frames.
The thread in the top of the reloading section by Capt tango is a great read on picking a press and some of the differences between them.
Then come back here and fire away with the questions, there as a ton of members on here with years of relaoding experience and were a huge help to me when I was getting started a few years ago.
One word of caution though its addicting
and Dont go into it thinking you will save money, sure it helps to justify it but the money you save you will probably be spending on more reloading stuff and components. On a brighter note though you will always have ammo and better quality than you can buy. Good luck
