my friend is trying to sell me 2 Lego store displays and I need help figuring out their vale. first one is the newest Chima one that displays Lavels fire lion 70144 and one other set with mini figures, new in shipping box. the other set features Star Wars AT-AT walker and snow speeder. both these sets light up and are displayed in a plastic box. Any ideas on what their value may be. He thinks they are worth $200 and $400. I would appreciate any help as I am a newcomer to Lego Collecting. Thanks
