Wish I would of known that about a year ago. We had several unused rolls of the 14" sitting around after we went to inkjets and dumped the OYO's. The OYO is a workhorse but having to dump 4g's on failing print heads every few years was getting to be a wee bit of a problem.
Contact SPSI. They used to be OYO dealers and maybe have a few boxes of film collecting dust on a shelf that they'd unload cheap.
