Credit cards are good, if you will pay them off every month. I use mine to get rewards, and it's like getting an interest-free one-month loan for everything that I buy. I get about 1% back, which isn't a ton, but it's good for no effort
I recommend Capital One. They would give a credit card to a monkey.
And Re: Synic saying "The credit card company doesn't make any money if you pay off your debt every month," that isn't entirely true. Credit card companies still charge every store you purchase at a small transaction fee and then a flat % of the purchase. (MC and Visa charge roughly 2.5%, and AMEX about 3.5%. That's why a lot of places won't take American Express and MC/Visa like having those annoying commercials to remind us about that fact constantly.)
