Michael, I work with Curt and I would love to have him check me out in his, but honestly I just think doing it in a cub with floats is the coolest thing around. If I had the 3k laying around I would do it, but for that money Crazy Horse is calling my name. Brown's is $1200 and from what I have heard is an experience you won't forget.
Tony, I agree %100 that anyone should get experience before teaching. I am just doing a little research before jumping in. I just want to do it with the least ammount of "learn the hard way" mistakes. Honestly it would just be convenience to be able to teach in a seaplane, not something I aspire to do right out of the gate. I guess call it a bucket list thing.
I just want to be able to legally fly one to get theat experience for down the road. I know a few private owners who would like to have a CFI along for the ride. Right now, a Beaver and two Huskies on floats at my home airport....I get the itch walking by them.
