KiteitRight is owned by a very friendly and knowledgeable UK kitesurfer. He rides Slingshot/Brunotti but also tests and knows what he sells including North, Liquid Force, F-One.
He also keeps a good level of stock (many of the UK online shops don't) and seems to have a way of getting what he doesn't have in stock quickly.
I know he ships internationally all the time.
