Looking for a 30 to 40m used yacht. Which yards should i look?

Hi All,
Im looking for a used 30 to 40m yacht which has a range of atleast 2000nm. My options currently are some classic Feadships and Codecasa's and a Trinity and a Oceanco.

I would like to know if any of you have been on the 1990 Trinity or the 1994 Oceanco which are on sale in Florida. I dont want to mention names here but am sure you could find out which ones these are. Is there something to watch out for? I havent been on them yet.
