Medley seems to be the only one available here so far. I have mine from 5LittleDiamonds (she was a late birthday gift from my parents), and I've seen quite a few people posting about getting them - but I've not seen as many posts for Twilight or AJ. I'm curious to see those two in person.
Medley is gorgeous though. I highly recommend her. She may be my favourite plush so far, because she's entirely new.
