I cannot see the US market, but I can tell you that a decent Autogyro here in France costs at least 50% more than a top of the range Aircreation trike. Add on 20% more fuel and the longer runway required and my point is made.
That is not to say that I would not like one!
A want Santa to bring me a decent motorbike so that I can keep up with my wife when she is on hers.
I also want a Gopro Hero3 Black, but they are not shipping to Europe yet, and when they do they will charge 40% more than the US price! Still going to get one though.
