I have seen them on the internet but would have to import them from America.
Just remember to account for VAT, customs handling charge (about £10 if it comes through the post, a lot more with some couriers) and if you make a very big order customs duty (afaict you don't start paying customs duty until your order value is over £200) delivery and payment handling charges.Why don't you import one from America? The exchange rate is $2 to the pound.
