I am also looking to buy the 1/6 scale Sideshow Gamorrean Guard. I am offering $200 (USD) + the Star Wars 12" Gamorrean Guard (Kay-Bee Exclusive) Figure by Hasbro. The figure must be in perfect condition.
My 12" Hasbro Gamorrean Guard is in brand new condition and has never been removed from the box. It's an excellent sculpt.
Please PM me if you are interested.
Here's a picture of the 12" Hasbro Gamorrean Guard:
