I know Hasselblad equipment is excellent quality made to the highest standards out of the best materials and closes tolerances when new, but many of the Hasselbads on the second had market a fu**ed with many years use/abuse, because pro's don't pay the sort of money Hasselblad equipment costs just to look at it they have had hard consistent use over maybe 20, 30, 40 years, the mistake amateurs make is thing that they are going to be buying reliable equipment right out of the box without a complete service by a professional repairer that should be factored into the cost.
