   That's what Tom says. He's been looking for one for years.

   Tom and I are working hard to try and find a way to get one or more of the chassis. The problem is that I don't have a truck AND the warehouse that I use to store and ship from is probably going to go away SOON. I no longer have access to the forklift so loading on a truck would be a problem even if I could get it there. These aren't complete chassis anyway, they're just the CPU sections.
