The material in the book, like most of the Tribe 8 books, is great. The problem is that the scan is quite poor - pages are crooked, warped (i.e., the text is skewed or slightly smeared), and there are various glitches and artifacts visible (e.g., hair lines down the pages). The scan resolution is acceptable but could be a lot better. For $8 you might be getting your money's worth, but I definitely wouldn't pay anything more.
