One word of advice I can offer is to never ever get loading data from websites like this one. Only get data from the powder or bullet manufacturers. There are some people who know what they are talking about on the internet and some who don't. You can never know which one you are "talking" to so why risk it? I have been reloading since 1977 and I have never broken this rule. With all the multitude of loads from the big companies who make the components AND do pressure tests, why even look elswhere?
Beyond that, I'd say start with just the basic tools. You need a press, dies and a powder scale. You can get by with nothing more. I know - I started as a kid and had no money so had to start with the very basics. IF you decide you really enjoy it, you can then add a powder dropper to speed your operation up. A case trimmer and deburring tool will soon need to be added if you are shooting a rifle that stretches cases to the point where case mouths are jamming into the front of the chamber pinching case necks and raising pressure. You'll find the case trimmer very handy too if you reload for a revolver and try crimping cases when you get a batch of cases with varying lengths and crimp some so much that they won't chamber. :) I've been there a time or two when starting out.........
I like the RCBS brand but have a little of several other brands that I like too.
To sum it up, start with the basics and be careful, methodical, conservative and get data from a safe source! Oh yeah, about saving money......well, theoretically you will but as soon as you realize that you are saving you'll start shooting more and there go your savings! Have fun.
