I know, repainting can be frustrating.
I started a thread here for the AT-43

The minis for the game are plastic and are prepainted. The picture is a stock photo but the minis look almost like the pictures when you buy them.
I'll take some photos of the mod I did to the Walker, Like I said in the thread above, we are still moving locations at work and not have much time to do anything.
