Nothing wrong with the good old C207, for some reason the older models seemed to fly a little nicer and could carry a lot better payload.
I happened to be in the right place to see some photos of Kakadu Air's MNN, when it was privately owned by a little old gentleman who had purchased it brand new complete with wheel fairings it did look rather dandy! Pity it didn't get a bigger can of climb performance installed prior to leaving the factory.
For tooling about into short strips and still reasonable performance you couldn't beat the late model Aztecs.
For true lust a Cessna C310R with some IO-550's, leather interior, colour radar, moving map GPS and the Cessna avionics sent to Sims recycling.
