Gree is the only one with Jedi/Sith weapons.
Uh, did I miss anything? Shouldn't it be the other way around and the Gree Event is the only one that has Legacy weapons other than Lightsabers? I mean, you can buy the Sword of the Vigilant on CZ-198 for 500.000 Credits at Champion standing, but to my recollection, you can't get pistols or blasters from anywhere else other than the Gree.
Or is this about something OTHER than just swapping hilts and modifications around?
