Wow! Thanks for the replies so far. I never even knew superboat made that 30' Y2K. I'll going to look into that further. Also will be checking out used panteras too.
I put 80k as my absolute limit, but a 50k boat is even better- I figure $1000-1200 is as much of a payment as I can swing after I pay off my truck this winter.
I thought I wanted twins, but every time I have engine trouble with my Donzi, I'm so thankful I only have to work on and buy parts for one engine. Also with fuel prices, a single probably makes sense.
