If you have a computer with a sound card in it, a good place to start is a USB microphone (under 100 bucks) and, depending on your budget either a V2 pod or a cab emulator to plug your guitar into.
You can pick up a pod v2.0 on ebay for about 100 bucks which you can plug into a line in on a sound card.
Plug a cheap set of headphones into the headphones out of the sound card and you are ready to go.
There is enough free recording software(many threads on this subject in the recording part of the GT forum) to get you started and bingo, Bobs your father's brother !
