If you're looking for the Itoya books, check 
www.utrechtart.com

They actually have a store here in downtown 
Columbus, so I drive into town whenever I need 
another book.  (Which I think is going to be this 
weekend...)  They have excellent prices.

I don't know what they'd charge for international 
shipping.  You may want to get in touch with them 
before ordering anything...

Hope this helps!
