I too am after Qui-Gon purely for the head swap! Have only seen light up Obi who has had his head swapped already.I found both the Obi and Qui light up figures over a month ago, at a local Wally in Ky. I got them simply for the headswaps. I really do like the sculpting on the bodies though. They have some good detail. I just wish they had better articulation.
Well....the Mrs. wanted to get Chinese takeout tonight so, since we were venturing back out and I was so impressed with Qui-Gon, I picked up Kenobi - also just for the head. Amazing results. Fits even better than Qui-Gon did and matches skin tone perfectly. Love it. Makes the Hasbro Vintage / Legacy Collection Episode I Kenobi look like a bootleg.
