Where online can you find places that compare credit card rates for free?

Cardratings.com is a good site for investigating and comparing credit card ratings. It will ask you for some basic information regarding the type of card you are looking for (including rewards offered, credit limit range, and if you intend to carry a balance), and it will then return a list of credit cards that fit you criteria. This list includes the APR for each card. Bankrate.com creditcards.com provide similar services.
