I seem to recall something about Boba Fett having fight Vader in a Lightsabre duel at some point, so I assume he does have a sabre or two in his private collection.
(And in case you wondered, no Fett didn't win the fight but Vader let him live anyway).
I thought it was the other way around - Fett won but let Vader live because the whole galaxy would have been after him has he killed him, but again, this is IIRC
