Checking Boat Point, Yacht Hub and Yachtdomain there doesn't seem to be that many of them for sale.
You might want to check out this MKI S&S 34. It is built with epoxy not polyester resin.
Buy it for $18,000 and spend the same amount on it, you could end up with one of the best and most valuable S&S 34s in the country.
Disclaimer:- I am very closely associated with the vendor of this yacht.
