Actually, he has quite a few sabers (as you can see) in his collection. He will, at times, sell pieces of his collection if offered the right price. You must contact him directly and see which ones, if any, he would be willing to sell.
Good luck!
P.S. I missed out on the Qui-Gon because I didn't have the cash at the time, and someone else (probably from here) snatched it up! :'(
Oh well, you snooze, you loose!
