Given the options I'd take serenity(dangerous yes, but damn what a ride, and yeah, kayle=yum), then DS9(aside from the occasional crossfire a trader here could make a ton of cash and be up front for a lot of history), then the enterprise(preferably D, that thing was a luxury liner), but if I had more to pick from, I'd take post peace keeper war Moya, or Lexx after it eats earth(or in that proffesor dudes spaceship full of naughty school girls....).

Also might like to take a spin on the Heart of Gold, the Bebop or Outlaw Star.
