Do Androids Dream of Electric Sheep?

I read that book probably 20 years ago. After i had seen Blade Runner. I just watched Blade Runner, Director's Cut tonight, another one of my all time favourite movies. Rutger Hauer is electric in it. But was Deckard a replicant or wasn't he? Director says yes he was but in the book, Deckard wasn't. Good website that lists for and against Is here. I prefer the Director Cut ending. The original was too cheesy. The ending is still ambiguous but it suits the movie better.
