There are many endoskulls out there on the market, from Icons to HCG to Sideshow Collectibles. But only few are still available for purchase. Sideshows Endoskull bust had been most popular so far and almost unanimously hailed as the best bust out there. Produced by Sideshow in partnership with Stan Winston Studios in 2006, the skull reproduced the image of the endoskeleton from the fiery title sequence of T2. Personally I also think the SS mold is far superior to the other ones with its mean, tilted look of the endoskeleton from the title sequence. As far as I know however, there are small differences from the movie version like the size of the CPU port, slimmer lower jaw and longer, more skeletal lower teeth. If someones looking for the most accurate endoskull its from Japanese M1 company which had Jim Camerons approval and endorsement on the packaging and was seen in his office. It also comes directly from Stan Winston molds. Sure, the Stan Winston Studios co created the SS bust but they resculpted it therefore it has some minor differences. Overall the Sideshow version blows my mind and looks far more impressive in person. Pictures make it seem as if the skull is much more silvery than it is when in fact its very metal like in appearance. Those go for anything between $1200-3000 even
