I meant that high-rated bonds are a higher risk than T-bills. Sorry, that wasn't clear.

Moody's and Standard & Poor's are two of the big bond-rating companies. It looks like you have to have an account with each to view their research on their respective websites. You be able to get at bond ratings through the brokerage (online or brick & mortar) you will use to buy the bonds. I believe you can buy T-bills directly.
