I scored mine on ebay after passing up bootlegs for years( ifigured i would run into a decent copy eventually). But beware of crappy copies(people sell em as the real deal-even on half.com and ebay). Look for the Video City issue, in the oversize case.
by the way, the book is also great, and obviously goes into greater detail. I highly recommend it! and whatever happened to the soundtrack by Herbie Hancock? I don't think it was ever released!
