A girlfriend of mine has both a 26 Donzi and a 24 'toon.... guess what one she spends the most time on??
I think shopping around is your best bet... go to the dealers and see what different ones they have in inventory, what you need for amenities (porta potty) and the different layouts you like...
then start scouring craigslist....
lots of financially distressed boats to be had!
