The great thing about ham radio, it really is an inexpensive hobby to get started. Now, once you get into it, you can spend just about as much money as you want (or have access to). But a Bao-feng handheld that costs around $40 or so can work the local repeaters on 2m or 70cm and is a fine way to get started, learn the lingo, etc.
I encourage everyone to give it a shot, and join up with a local AUXCOMM group or whatever you have locally. I have to admit, I'm not as active with our local group as I'd like to be, due to competing demands for my time, but I hope to eventually work things out to where I can get more active.
