Mr Float, certainly good comments here, though I think the person who said that on the "Cabrinha have picked the wrong name" thread was having a sarcastic dig. However you are prefectly correct. Used I think is the way to go, I have two Kites (04 and 05) both Cabrinhas, bought each at 50% new cost and were only used a dozen times so pretty much immaculate. The Crossbow will come out on the second hand market before you know probably early next year, but they all do the same thing, give you serious enjoyment.

As for the cost, ha, Kiting is cheap, the more you go out the cheaper it becomes I guess, however, I do know of hobbies that will cost you in excess of $500 per hour and not much lower than $200 per hour.
Cheers, have fun with any gear, and bring on the wind.
