Hey all,
I just found this site, not sure if you are aware of it.

They make their own lexan bodies there and they sell them for cheap compared to proline etc. You can get buggy and truck bodies from 14$...
The guy who owns the company posts on another forum all the time and he says if there is enough interest in different types of bodies, he will make them.
Personally I would like to see some cheap 1/10 scale bodies.
Plus you can get custom vinyls for like $5. Can't beat that.
