Your first question is cockpit configuration. Around hull #450 it switched to a more 'sit in' rather than 'sit on' configuration. Down below they lost a quarter berth and gained some galley space (and a locker in the cockpit).
Have a look at both types if you can. If you like the later one better, your search is even harder since there are fewer around, and they sell more quickly. If indifferent to type (and practice doing some jib trimming too), then the pool is greater and you'll find a good boat. Moisture in the core is the thing to be aware of. That is color blind to cockpit type!
