The Exactas, especially the Varex series are great cameras built to take punishment that will destroy most others. I'd suggest the VB as it has electronic sync and the finders can be changed to either waist level or accept a metered or non-metered prism finder. When these were out, many companies made 1st rate lenses for them and today most can be had for cheap as the system fell out of favor as it did not keep up with the developments such as instant mirror return and the control layout did not conform to what was to become the norm.

Today, a serviced body and a system built around it can still knock off many newer and electified cameras.
