What you want is to start building a savings account. That is your "emergency money". It's not fun and won't allow you to go buy that new shiny thing at the store. Five years from now it won't have you cursing yourself for spending 3x as much for that shiny thing as it actually cost.
Get a bunch of applications. Spend an evening making pro/con lists of the terms and conditions. Realize that there's a reason it's such a pain to decipher them: they are out to screw anyone who is too excited about having that purchasing power to consider it an idiot tax.
On the other hand, all of that interest being paid by people who don't know any better is part of what's keeping our economy propped up. It didn't work so well with that subprime home loans thing, but don't let that stop you from doing your part to help out your fellow man.
