Yeah, I have a kit that's about 2' tall when completed as I recall (it is in a bag since I bought it) vinyl and white metal. I t was a Japanese kit from about 10-12 years ago IIRC.
Sideshow have one now that's built that is full size and looks great, IMHO.
You're talking about the Argonoughts 1/4 scale Endoskeleton. It's actually only about 18" tall when built. It's very nice. As I was picking at the one I have last week I discovered that the NECA 18" figure is very much the same sculpt. Only it's injection molded. I am now considering putting the white metal hands and feet on the toy and giving it a better finish.
