Payment can be made by check, money order or wire transfer. Or, you can pay by credit card using the PayPal service. Super 8 equipment is complex and typically 20 or 30 years old, so condition is somewhat variable. Please test before any critical use. I offer a 6 week return privilege on cameras, and a 2 week return privilege on other equipment - this should give you enough time to run a film test.
Buyers are responsible for return shipping costs.
