In my opinion, (and this is what I am doing). I took the card with the highest interest rate and put all my extra money towards that. When they is paid off, I will take that money and put it towards the next highest and so on.
Also call your creditors and see if there is a better interest rate out there. BOA and Citi are excellent to work with and will lower your rate if you explain you are trying to pay your debt off.
Some members may disagree with me and that is okay, because what works for one person may not work for the other.
I started at $54k in debt and finally down to $20k 4 years later and I did with through a DMP and some by myself. Just don't get discouraged and hang in there.
Good luck!
