I see it on Amazon used for $110. Expensive, but seems legit.
Man wish I didn't use mine as a mousepad for 2 years. Kinda thrashed.
Fantastic book, just perfect size and thickness for a mousepad..
The book is out of print, so you will have to buy it used.
A copy in very good condition is for sale on the Magic Cafe for $65 plus shipping. You need 50 posts to be able to see the Books for Sale section. The book typically goes for $60 to $65 with shipping.
