Lochearnhead in Scotland. There are three operators on the lake but I flew this summer with the gentleman at the west end who also owns the canoe and water ski centre. If you PM me and are seriously interested I can pass his details to you.
He operates a nearly new yellow Husky which has the additional advantage of being fitted with both floats and wheels.
He is thoroughly professional and very expereinced.
There are several good places to stay locally. Flights can be had to Glasgow of course although I flew myself to Dundee (about an hour and a half drive to Lochearnhead).
I loved the aircraft and also the flying!
