A few others:
The Sulaco, from Aliens.
The Nostromo, from Alien.
Cloudbase, from Captain Scarlet.
Horizont dropships, from Mospeada (the third part of Robotech). Several others from this particular series are cool, too, and were reasonably well covered when Paladium was doing Robotech, since they had access to all the original concept and sketchwork...
Star Leaf, from Gall Force (similarly aged anime). Again, the other ships from this show are also quite cool.
While the Millenium Falcon has been mentioned, Star Wars has others. Track down the old SW-D6 version of "Stock Ships" for a few of them, with deckplans. The various Dorling-Kindersley books on SW are also good sources.
The Bebop, from Cowboy Bebop. Many other stealable ships here. The Tokyo Pop folks have been printing little books about this show, so the art should be findable (Borders, in the US, seems to have these fairly often).
Most of the Babylon 5 ships are WAY too big to reasonably do deckplans, but that doesn't keep them from being cool.
The Ragnarok, from several versions of Final Fantasy. For the ambitious, deckplans of one of the Gardens from FF8 would be rather cool.
