Ebay a 9600. Some out there look to be in good shape. Even if they are not, as long as you keep plastic wheel to plastic wheel (or metal to metal, metal and plastic are not interchangeable) you can switch out the cases as needed should you not like the case of the new unit. At one point, the service manual stating how to disassemble one was in the free on the web. It was on google but I cannot locate the link at this time.
