Indeed, it is expensive. Well, I'm a little disappointed with that book. That's not a bad songbook, but it could be much better. First, all but 2 songs are slow themes. No fight themes!I guess that is not representative of the FF OSTs
Then, almost all arrangements are easy, and beginners should have fun with this book. But, I really often change some things when I play the songs.
I guess if you are an huge fan of Nobuo Uematsu, this book worth its price, because that's the only FF ukulele songbook (the only vdeo game ukulele songbook I guess)... But remember that this book is not perfect.
