I really enjoy listening to pretty much anything the folks at Full Cast Audio have done; http://www.fullcastaudio.com/

Other than their work i've recently listened to Bill Bryson reading his autobiography, "The Life and Times of the Thunderbolt Kid", as well as Malcolm Gladwell reading his book, "Outliers".

I usually listen to the previews in the iTunes music store to get a feel for the narrator.
