Establishing Credit - Best Credit Card for a college student?

[playtowin]

I'm currently in the process of establishing credit... I normally only use a debit caard (or cash), and I have no student loans. I have a student credit card through my bank, but from what I understand, it's really not doing anything for my actual credit score (I believe its simply designed for students to get used to handling a credit card). Anyways, my parents think i should apply for a credit card, and I figured 2plus2 would be a good forum to find out the best way to establish credit/get a credit card for a college student. any ideas?
