Hi Bobblebob,
I had the same problem, trying to order the guide from the Netherlands.
Amazon.co.uk was out of stock, but had a healthy selection of 2nd hand guides which (from the descriptions) were purchased purely for resale. This is an appealing option because it keeps the shipping/dispatch close to home.
Alternatively, what I did was to order from the US. I found a website which was willing to ship the book anywhere in Europe through a company called International Checkout. I managed to get my eager paws on it this way.
I looked at that website though and saw they were out of stock. I fear for you that the impending christmas has depleted the last stocks.
My advice would be to scour US sites looking for one that will deliver to the UK - getting the guide in the UK is very hard as it was manufactured exclusively for the USA (if I'm not mistaken). Also, get in touch with anyone you know in the US so that they can perhaps mediate the shipping process.
Good luck and happy holidays,
Phy.
