I purchased a Fuji GW670II camera from Ebay. The camera arrived yesterday and is in magnificent condition. It literally looks new. On the other hand, previously I purchased a camera from Ebay that was advertised as clean. I open up the film door to find not one but two social security numbers carved in heavy lettering into the metal. I returned the camera and what a surprise, the seller places the camera right back onto Ebay without disclosing the additional details. Out of any of your used medium format purchases made online, do you have a best and worst story?
