What is the cost of a current, similar megapixel and sensor size back? Obviously nothing exactly similar is available, but close enough. Hasselblad has 16Mp 37mm square back that may be somewhat comparable. Then take 10-15% per year off that price for it being second hand. Needless to say you will not get close to your original purchase price. But why would anybody pay more today for an old back?
