My advice - if you see a really good deal for a model, grab it, but give it a good looking over when you receive it. There should be little pegs and holes for the pieces to sit in. This thing even had "By toMi" painted on the back and it was transferred over. We didn't see this until we were trying different paint samples on it.
As the movie gets closer and MFU becomes more collectable, I suspect we will see more and more cases of this. Just be careful.
