You can Google Ross Yerkes to get his phone number -- as I recall, he doesn't have a website.
I really like these cameras and lenses, but unfortunately mine need servicing and I just can't swing it at the moment. I have one of each of the bodies -- Six, SixMM, Super 66. I love the way the bodies handle, with their vertical orientation. My sense is that one of these that's been given a going over by him will be very reliable. And the lenses are quite good.
