I would definitely go Clipper II. Better corrosion treatment. Where you live you cannot avoid the salty atmosphere. Wash down as suggested and dry it before you put it away. Think of using an electric heater under the machine.
I would look for a machine with high hours but plenty of years left. As a private owner you won't get many hours - often less than 50 - so a machine with only 300 hrs left to a rebuild will give yo 6 or more years use.
For example mine has 500 hrs left but will use then in 1.5 years. Buying a machine like that maintained to full AOC for commercial transport would save you on purchase cost then give you 5 or more years of use.
Take a look on
Aircraft for sale: private Jets for sale, helicopters, piston planes to get an idea on price.
