My list is the Enterprise-D battle damaged, Enterprise-D all computer voice sounds; a fitting tribute to Majel Barrett-Roddenberry, long overdue here!
Other ships would be the Voyager and Defiant as they both have a lot of multiple release value for DST.
Sorry to say but a lot of the ships mentioned on the board here are all great but most likely will never happen as they are one offs from various episodes and movies and really have not sounds clips to offer or would even be good for multiple releases of the model. Look at Diamond's business model and you can see they like to get the most profit they can out of there electronic ships.
