Redding makes excellent products in my experience. As far as dies are concerned, what you'll need to get started is a full length die and a seater die. I'm sure Redding makes a set that contains those two dies. Please note that I'm not talking about their Competition dies. You could go that route, but their Comp. dies are considerably more expensive. I'd get started with the standard dies if I were you.

Personally, if I were you I'd buy a reloading manual and read up on the steps to reloading. It will explain what equipment (dies, etc...) you need. Hornady, Nosler, Sierra, Lyman, Speer and some other companies put out some good reloading manuals. You could also go to RCBS's website. I believe they have an online guide.
