Do you have a friend who lives in Great Britain who can buy you one?
Richer Sounds has them, but they say on the website that they are only available in the stores (ie, not online). Only 20 Pounds ($40).

The owner is Julian Richer, who is also the general partner of the investor group that owns Cambridge Audio. That is why you will notice a large amount of discontinued Cambridge gear for sale brand new at Richer. He basically uses his stores and website to clear out all the old inventory no matter how long it takes...
