Pretty sweet looking rig, I kind of wonder who their target market is. 135K is a good price for a new light aircraft, considering a decent used float equipped C-185 or 206 can run you upwards of 180K or more, and a Beaver for a quater mil, (floats themselves can cost half the price of the airplane they are fitted to). I see a danger as Les pointed out, water operations are extremely challenging, even for the experienced. I have six seasons doing just that, fun but unforgiving.
My fear is that the nuveau riche may see this a plaything, much like Ferrarris, Lamboughinis and such, and end up like the Thurmon Munsons who, with 500 hours, think they are Buzz Aldrin, and can fly their own Cessna Citation better than the instructor training them, killing themselves, their instructor and seriously injuring their passenger, but I digress.
If a person with the desire and discipline, (and ablility) to make the dedicated effort to fly, this might be a satifying little beast to own.
Me, I want a helicopter.
