To the OP, depends what you need it for.
If you are only looking to travel in the US you can get the AirTran rewards VISA. There are two options, but one is free and for every $1,000 you get 1 pt, 8 pts is a ticket, 16 for roundtrip. So it usually comes out cheaper than other airlines (my delta card is 25,000 pts for roundtrip so $25,000).
If you are looking for a zero interest card to take care of some of your expenses while you hit a rocky time, or lost your job, etc, then there is the Clear Card by AMEX, no annual fees, no late fees, no APR for 12 months, etc
If you want a good rewards card, you can go with blue from AMEX. Good rewards, just AMEX isn't accepted in many places.
