If you can get the book from a European store I would advise to follow that route. Just in case something goes wrong you won't have the hassle dealing with American Stores.
But having said that, I bought mine from . I actually ordered it through the Amazon site as it was still cheaper than ordering direct.
I definately recommend getting a cover while you order anyway. I didn't and now don't want to pay the extra shipping on top of the cover cost. So I made my own.
