CutThumb, if there's a "best Studio Scale replica" vote, this model gets it.
Julien, paint it the way you want to! I don't like the brown either.
Joe - I have drafted a file to cut a disc for the lower body, to act as a platform for the rest of the armature to rest on, and for the legs to screw to, and to shore it up (mine is similar to yours in thickness and it does push inward a little, if left to it's own devices). I think Mars' metal armature And Julien's mount is great, too.
I love seeing every one's solutions to the same problem!
