Kitewing

I have done a little windsurfing and have always wanted to try kite boarding.  I was talking with a friend about signing up for kite lesson and he mentioned a Kitewing.  I didn't know what it was but I was interested.  He had seen a picture but didn't really know much more.  I did some looking on line and found the manufacturer's site: http://www.kitewing.com/.  It looks sort of like the sail off a sailboard except it is more hang-glider shaped.  It looks like fun and it could be used with multiple different "rides."  Here's one of the many YouTube videos: http://www.youtube.com/watch?v=7vmjf82Oq_Q&NR=1.  Looks like another fun toy to spend some money on - just what I need.
