Well, thanks for the advice everyone. I asked again when I went to test play some more flutes. It appears that Miyazawa Deutschland have ordered a-444Hz as their standard pitch, however the owner of the flute shop I went to thought that was too high and put a special order in so that his all come with a-442Hz.
I narrowed my final choice down to the Miyazawa PA-202 or Pearl Dolce with the Miyazawa having a more complex sound in my opinion (and my husband's, after all, he has to listen to it), so the Miyazawa wins and I should be able to pick it up tomorrow
