Special Comments:
I picked this one up for $25 as is.  He had a broken hinge on one of his doors, which I fixed with a dremel tool and a piece of an orange plastic gerbil exercise wheel.  This robot is monstrous in size which adds to it's charm.

Update:
I have been informed that this robot's name is "Super Giant Robot".  Thanks goes to fellow toy robot enthusiast Cal Johnson of the group Not Yet Dark for this information.
