re: Looking for a performance boat need opinions.

I would freakin' RUN from any Donzi, particularly the smaller ones. I have been around quite a few of them, and have yet to see one that I would want to own/maintain. Fountain and Cigarette are two of the best IMO and you should probably look at Formula also. Just my opinion, but an older Formula Sunsport is a lot more versatile/practical but still plenty fast for the thrill seeker in you.
Good luck
