I seem to recall (much to my astonishment) that certainly when I travelled last month the Heathrow branches of Dixons had all Leica cameras in stock, including the M9.
I think it was c.£4,200 but I was at that point somewhat addled. I tried to phone them yesterday to check availability / price as I'll be travelling again soon and am tempted, but no one seemed interested in picking up the phones.:bang:
