As Mark said, we are not supposed to put direct links to boats for sale, but I do not think anyone minds if we put up general places to look, so here we go: (in no particular order)
Ebay.com
boattraderonline.com
yachtworld.com
cragslist.com (even better - download the craigslist search program to search them all at one time)
yachtsalvage.com
projectboats.net

AND of course the best place to look is

It took me 5 years to find a 20 SF less than 1000 miles away that wasn't totally trashed. Being in FL you will not have that problem. I highly recommend being ready with cash in hand when you go to look at the boat or you will not have a chance. The guy I bought mine from said there were 25 other people in line to buy the boat waiting for pictures. I drove 500 miles sight unseen.
Good luck!
