49er,

I can answer the cost question.

I've been looking at the cost of various F16hp boats, including the Taipan 4.9 and Jav 16. New, $9-11K, depending on options. But used Taipain 4.9s are extremely reasonable and could be had for the same price as a new Dragoon--ah, and look what you'd be getting! Even though used Taipans are primarily in Australia, the exchange rate still makes them a real deal even considering shipping.
