Don't forget to check ebay - when I wanted my B&M lights last year, I ended up getting them from a German ebay bike shop. IIRC, BikePlus didn't yet have the IQ Fly (Chris Juden had only just reviewed it in Cycle, I think) so despite me getting the wheel and dynohub from them, I went to ebay for the lights. It was somewhat cheaper than anywhere else I could get them, even including the postage.
Make sure you set your search preferences to include 'European Union' locations.
