I am a Kite Instructor and Ozone Distributor in Chicago and I would be happy to help you. The new Ozone 2012 air foil kites just arrived yesterday and they are so nice! We also have mountain boards, buggies, harnesses, helmets with knits and kite specific snowboards.
As far as air foil demo kites, I have one 4m Access remaining since I have sold the rest of them. Here is the demo gear sale that I am currently having:
I'll send you a pm and get you all sorted out with everything you need. Thanks so much!
