I read the same review of the tiger gaff deck book. i also read the comments that in many cases, the people reviewing the book they "thought" was the Ellusionist Gaff deck book were in fact reviewing a different book put out by someone else at a different price.
Brad Christian even chipped in with some posts to clarify this.
i own a number of E produced videos and typically find them excellent. i have not seen this one yet. i also have not seen the accompanying book.
you can see a preview of the DVD here.

also i think some of the video footage from the deck preview is from the DVD.
