Digital Rev in Hong Kong have it for ?568 (ex postage I think), but you will have to pay vat. They are excellent and ship promptly. Just don’t go for the UPS option. http://www.digitalrev.com they are also on ebay under user digitalrev.
I’ve seen it in Dixons for ?799 also, though I couldn’t recommend buying from them, I had a terrible experience with them a few years ago – they wouldn’t replace a keyboard on a PC. I don’t know anywhere cheaper and have been keeping an eye out since I bought one myself recently.
