A credit card is good to have, just get one with a lower limit.
Actually, though, the best thing you can get is a check card. It acts like a credit card but is tied to your checking account, so you're pulling money from your account rather than charging against a limit. I use mine way more than my credit card. You can use it anywhere they accept Visa, MasterCard, etc. Mine is a MasterCard check card, but it's issued through the bank we use.
Besides the check card, I carry one other credit card and that is it! Many years ago (before I was even married) I bet I had six of those stinkers! CC companies show up on college campuses like sharks around a wounded seal! It's so easy to get a credit card at that point in your life, and it'll end up burying you in debt so fast you won't know which way is up! It took almost three years, THREE FLIPPIN' YEARS to pay off a mountain bike I bought while at Ohio State!
Man, it cannot be stressed enough. CC's are tempting little nuggets in your pocket. They are great tools, if used properly, but even a hammer can hurt you if you're not paying attention!
Personally, check card and checking account would be my first choice.
