A little over a year ago I was starting out just like scottd913. I purchased the "Lyman Shotshell Reloading Handbook 5th Edition" as Snuffy advised in his post. It is well worth getting if you are starting out and a very good reference even after you get your feet on the ground reloading shotshell. If you want to look it over good before you buy it some city or county library systems carry it.
As far as which press to get I went with a used MEC 650 and have been real happy with it. At least 95% of my center fire reloading tools are Lee. That also goes for my bullet molds and casting equipment. Lee products have performed very well for me. I'm sure many folks assemble great shotshells on their Lee Shotshell Loaders. I decided to go a step up in my opinion and go with the MEC for shotshell and I have been very happy with that decision.
Read and follow the Lyman book and keep safe in your reloading endeavor.
