I paid $200 for mine (through the generosity of a friend with contacts) which while expensive was a decent price all told.
I really like him and my son has loved the lights and sounds. They've done a great job of recreating a figure that resembles G1 Fort Max by reworking Generations Metroplex. That said, I think that G1 Fort Max has more cool gimmicks to him like all the blasters in the arms, waist and hands, the jail, the working lift etc. And I think Gen Metroplex makes for a cooler looking (as well as bigger looking) city.
So yeah, glad I've got him and I think he is very cool but I can't say I massively blown away. Surprised noone has postede a comparison pic in this thread yet so I'll pop one in. Will try to do a proper review during the school holidays when I have time :)
