1:4 scale T-800 ENDOSKELETON SIDESHOW COLLECTIBLES

This replica is by far my favorite. As always mine does not carry its rifle.

The arm joints, head and torso are movable, so you have some freedom to make it hold your favorite pose.

It is based off of the highly-praised Argonauts kit, so the details are superb. The head is redesigned to be slightly smaller.
Since it is a discontinued model and is a good size for it to be a collectible, it is still traded at a high price at auctions.
