as to cost, $300-400 would set you up with an RCBS Master Reloader's kit plus the non-included items you would need. You could of course do it for less or more, depending on quality of equipment you wanted to start with and whether you could find some good used.

Cost alone (saving money on ammunition) is probably not a good reason to get into reloading. Hand-loading is an activity and learning experience in its own right. If you are serious about it, you will probably want to explore the nuances of the many variables (powder, bullet, case, primer, seating depth, crimp, etc) which means building alot of ammunition just to test. If you are not serious about it, well ... maybe you should stick with factory ammunition.

But FIRST, get a good book (like Speer's) and read it through. The experienced folks here can provide excellet help with specific problems, but do not expect to get a comprehensive overview you need from reading the forum.
