I like Sedo for International traffic as they give you .03 guaranteed and geo target.I like DomainSponsor for my US names although they can vary and sometimes they go below 3cents if you have a lot of undesireable traffic.
Fabulous is good if your domain name is the actual keyword, they won't go off previous traffic so you can't put DVD keywords in if the domain was carsforless.com (just an example) even if the last site on the name was the biggest DVD store in the world.
There's also
www.goldkey.com but they are taking forever approving my names so no experience.
I look forward to any new options. As long as it will do International traffic and let me pick keywords and show me what the CPC for that keyword is so I can optimise the hell out of it i'll be happy. :-D
