Death star
Even if it wasn't a real sphere(which a guy in our town foolishly made), just with the super laser area, the hanger bay, the emperors room, some hallways, that sort of thing, I'd be all over it.
Could you imagine EU like a world devestator, that would be neat as well.
I'm not impressed with the BMF, though, so I'd probably want another falcon, lol.
but goign strictly by the question posed. .. I'd say. .. A Sith Lord Narceron fully articulated figure with slave girl harem.
