This book has previously been going for $100+ on Amazon/ebay, and the 2006 version still is going for that much. Now, I see the 2007 version is going for $10-12 plus $4 shipping either from the States or the UK. I have a stack of books I am working my way through right now, but I could not resist and just ordered it. 
Sharing here for anyone else interested.
Note the follow up post below…do not buy unless you can read German. :biggrin:
TmT, it looks like those books in cheaper version are in German language. Even I am eagerly waiting for this book to come down at a reasonable rate and its a big disappointment that it is in German. Please let us know if what you receive is English language.
Awwwww crap, looks like you’re right. In my excitement, I just bought a book in German HAHA. The good news is that wave reading can be done in any language…the bad news is I need to read the book in English first to figure out how lol
Have to see if they will cancel my order now.
