No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
If you have control of your spending you could save money and possibly incrase your score due to lower util by getting a 0% BT for say 12 months as long as you can PIF before the end of the 12 months and they dont close the old accounts down. Depending on were your are FICO wise, getting a ne account could lower your score.
IMHO I would not do it unless you can PIF in 1 year or less.
