i have inherited a mamiya msx500 which i know nothing about (point n shoot merchant) and i wish to sell it, can anyone tell me what a reasonble price would be....its not in bad condition and it works perfectly, it also has a vivitar MC tele converter,a soligor auto-zoom 35-70 F2.5 lens with it, and i have an olympus auto-zoom 100-200 lens but this doesnt fit the mamiya, any help would be appreciated thanx
