Too bad you want scale, Playmates' Defiant is huge and beautiful, easily their best effort to date, and one of their only ships to use ACCURATE sounds.
These are all the ships I want unless I find somewhat good scale Defiant and Voyager toys.
I just might go for Klingon, Romulan, Cardassian, Breen, and Jem Hadar ships in the future (maybe Ferengi, Tholian, Vulcan, or Andorian) but I'd want a Borg cube as large as my coffee table. Ha! (Maybe a sphere the size of one of those exercise balls could work though).
