The scan is readable. Some pages are slightly angled and mildly blurred due to the book's binding. A few pages are out of order, but all are accounted for.
This book is long since out-of-print and hard to find affordably, even on e-bay.
Don't waste your time looking on P2P networks or torrent trackers trying to find this book. This is probably the only clean digital copy on the internet right now.
Overall: The price is fair, and the copy is game-worthy, but I expect more from a paid-for pdf. */***
Things that would improve this e-book:
Cut the pages out squarely and rescan
Use Character Recognition software to digitize text
Be more aware of page order
Add logical bookmarks for faster navigation
