we actually have the international versions of the ranger and muddie on sale over here in the UK, but I always griped about why Casio don't make the atomic versions of everything available in the UK because this is prime atomic territory here! Though I think they listened in the case of the ranger
I was very excited when the Covent Garden store told me they'd be getting all 3 Navies in. But then they called and said they weren't getting the Frog. And then they said no atomic Muddie! I was gutted. But it makes the chase and ordering from Japan more exciting.
