That's mighty expensive for a plastic robot head (although, I can see that in time you will get a return on ebay). This is what a review of the package says (US version):
"If you're a hardcore Terminator fan you're probably going to see cool written all over this collectible.
First, it includes a T-800 14? Endoskeleton head that plays sounds from T2 and has glowing red eyes. Next, it features the Terminator 2 Skynet Edition on Blu-ray plus both the Extreme Edition DVD and Ultimate Edition DVD. Between all of these you basically get every single Terminator 2 special feature ever released on DVD. Additionally this one comes with a digital copy of the film for iTunes or Windows Media.
I think this is very cool, but really only if you're a hardcore Terminator fan. The reason I say that is as far as the movie goes, it doesn't really contain anything that I can see that you can't purchase separately at a significant cost saving. So really, you're only buying this package for the Endoskeleton head.
UPDATE: The head is made of chromed-plastic. So that's an expensive plastic endoskeleton head. Like I said, this collectible is really for the hard core Terminator fan."
