Gone with the Wind Kites is sadly gone
Steve still sells Prism Kites, top link at the right or www.kitekids.net
sorry no quads. Watch the swap meet below or post a request in the Wanted section, somebody might offer you up a great deal.
Otherwise the links on the right contain some great dealers, A Wind of Change run by Kent is a great source for quads and a good friend of "The Forum". If you don't find what you're looking for in Florida give one of them a call.
