I'm buying a kite in the next week or so

Up to body dragging with the instructors kite. I'm considering: Naish Boxer. Airush Flow, Caution Spitfire, Cabrinha Co2 on my short list, but what do I know! Any useful comments from the experience of the people who use this forum would be appreciated before I hand over the cash.
