Wow. Have I got one cool eBay Prop-Watch for you today. Fans of James Cameron and "Aliens" will want to pay extra attention, as this concerns you specifically. It's rather expensive -- though not ridiculously so -- and available for local pick-up only in Indiana, but the right fan will jump on this rare offering regardless of expense or distance.
"Aliens" was recently named the number one greatest movie sequel by Empire Online. It was a potent follow-up to Ridley Scott's 1979 original, giving fans more in just about every way, especially when it came to the titular aliens. The item up for auction in today's Prop-Watch is actually a promotional item more than it is a prop... but what a promotional item it is for you alien lovers.
That thing stands 7 1/2 feet tall. It's an original in-store "Aliens" display from 1986. It isn't exactly in pristine condition -- there are multiple cracks in the body of the beast and the tail is gone completely -- but are you really going to complain when 7 1/2 feet of "Aliens" awesome is standing in front of you? Just be prepared to make the trip to Indiana or hire a mover. And prepare for the opening bid of $999 to rise, because my guess is that it will.
