Giobbi has a book dedicated to switching called the art of switching deck.
Benjamin Earl also has a a video on deck switches.
Not necessarily a "deck" switch yet it is...Shawn Farquhar has a nice move using his turn to the side grab ahold of his suit coat that is phenomenal.
I've heard good things about "Cooler Deck Switch" gimmick by Christian Engblom. Although, I've heard it's unnecessary and is more for fooling magicians than anyone else.
Real Deck Switches is also good. It's kinda ballsy but there's no gimmick.
