I purchased a Japan model from HKBNS £779.99 all the camera had english on it and initially the menu was in Japanese yet once selected English it was basically same as UK model, apart from the obvious UK warranty and missing the rest of EU languages which weren't needed in my case.
They knocked the price down some so didn't get the full amount of duty but i did end up paying some, but the total was far less than the UK cheapest price.
