Only US format is missing a key (it's so annoyed, borderline arrogant!). EU format has the right number of keys so touch-type or swap them round, I have a laptop with a German keyboard and it's mildly annoying but doesn't really bother me, not as much as half-height enter keys anyway.

Very Tempted because of the saving. It doesn’t look too different from the pictures if the y and z are swapped but those character changes will annoy me. Does anyone know where you can buy a conversion kit with the correct keys?
