The "B" at the end of the model means that it is the UK model, not a foreign import.
So in regards to the last reply to your question explaining the "K" model is the UK one for tv's, that is incorrect, we use the "K" prefix for small items like dvd players, recorder, camera's etc. that are in the colour Black.
