Pandalove, I've forgotten where you're based...
Amazon.com have it to buy new from$39.99 but they've also got "used and new" from $4.49
To be honest, I wouldn't say it's worth almost forty dollars, it's interesting, but you won't learn much more than you will from Jeff Tamarkan's book and there's not a great deal of re-listenability (I think I just made a new word! YAY!). There's only one song, a demo-ish version of "which side are you on?" from Windows of Heaven, the rest of the double album is an interview with PK.
I'd definately recomment you shop around a bit before spending too much on it.
