I've read everything Carl Hiaasen's written (some books multiple times) and two or three by both Tim Dorsey and Christopher Moore.

Dorsey takes a bit of getting used to, what with having a psychopathological killer and an always-high doper as recurring protagonists. With Hiaasen, you get the impression that his male protagonists are romanticized versions of himself. If Serge and Coleman are romanticized versions of Tim Dorsey, he's a pretty fucked up dude.
