Some good dubbed anime:
Baccano
Hellsing Ultmate
Code Geass
Death Note
Fullmetal Alchemist Brotherhood
Cowboy Bebop
Ghost in the Shell: SAC
Beck
Cromartie High School
Steins;Gate

That is just a small list of really good anime with really good dubs.

Also don't forget to check out movies especially those from studio ghibli as they all mostly have great dubs.
Sword of the Stranger also has a excellent dub.

And you are lucky that the dubs for Accel World and Fate/Zero are going to come out sometime later this year. I know for sure that the Fate Zero dub might end up being one of the best dubs and I really can't wait for it to come out.
