I flew the Rheims Cessna F406 Caravan 2 in the early 90's, and it was a fabulous A/C. 2 500hp PT6A's, giving great reliability and performance.
CAT 1, with a simple but effective Auto-pilot and very straightforward and forgiving to fly .. but equipped with everything you need.
Good baggage capacity behind engine nacelles, and in the long nose.
Unpressurised .. therefore cheaper, but still cruised at 240kts TAS (retractable gear)
Handsome aeroplane as well ...
I don't know too much about availability, or lease rates at the moment but I could not recommend it highly enough ..
