In that price range I would rather have a new Jinbao than a used anything. I've had four Chinese horns, and they've all been good bang for the buck. If y'all can put the $$$ together for a Mack or a Wessex, good, but I bought a Jinbao English baritone from a Chinese vendor (i.e., just about straight from the factory) and played it in a brass band for 5 years.
