re: Recommendations on Credit Cards.

You shouldn't worry about interest rates because you shouldn't be carrying a balance. Some of the best rewards cards have annual fees and most of the time it is worth paying it because the rewards far out weigh the annual fee. A lot of cards will also waive the annual fee in the first year. It really depends on what type of rewards you are looking for (cash back, airline miles, hotel points, etc).

Also, do not cancel your oldest cards (they help your credit score the most).
