I know nothing about them except what I posted unfortunately.
I would say your best bet would be to build up a lot of PayPal and put up a Wanted thread in the Marketplace.
I can tell you that there was 25 of those Z Ringers made, I have owned 3, I have lost 2. The other one will not be sold until I get another 2-3 off people. And you are correct, they are not cheap to find, running between 60-80 bucks
