hey mate ,
i did it , it cost me at around 359 quid , since the day bank exchanged the money , apparently British Pound was on it's low , 1.5557. if you are lucky you might be able to get it at 349 or something like that.
as for costs , it is the device , which i chose to receive without the UK plug charger ( i use a converter ) and the 29 USD for DHL service. no other costs so far.
cheers
