There are three of those I feel that I must have, but I'll have to wait until I actually have money.
Qui-Gon, Obi Episode 1, and Quinlan Vos. I think it's fantastic that he actually made an expanded universe saber. There's this one place I saw that made an awesome Asajj Ventress set. I tried to get two curved hilts like Asajj's from Photoninnovations.com. Boy, was I not pleased with the craftsmanship. They were terrible.
