Looks like you're convinced not to go the trainer route. My float plane is a Falcon Ready ( [link]http://www.falcon-trading.com[/link]). Its a 40 size that flies great. It's all plastic and foam so no rotting to worry about. They also have a Cessna on floats (this was not available when I bought the Ready...would be my plane of choice). This one is a little bigger.....60 size. A guy in my club has the Cessna. It looks great and he claims it flies even better.

We have a cabin in northern Wisconsin. The day I took my Ready out on its maiden, I had 15 boats in front of our place. Did loops and rolls with no problem. Had to buzz them a few times so they would move so I had some place to land. This winter I modified it with flaperons. Can't wait to take her out in a couple more months.
