One of my personal favourites is the Rockwell 680/685. There's quite a lot of them in use in the Caribbean and Bahamas flying the inter island charter routes. It's fun flying too and the high wing is an advantage in tropical sunshine. I suspect though that you'd have to do a lot of research on the marque in order not to get slightly stung. The simple selection has to be the Twin Commanche. It has it's foibles though so a knowledgable conversion instructor, experienced on type, is a good idea.
