recent brute-force work factor calculations

Does anyone know of a recent brute-force work factor calculation for the various common symmetric ciphers? I.e. it'll take X 3.2gh Xeons Y years to brute cipher Z. I know there's a table of these in Schneier and there's the "Seven Cryptographers" paper but they're both pretty old at this point. I'm just looking for an approximation. Thanks. Eric
