I own and regularly use three Hasselblad bodies (two 500CM's, and an ELM). They are utterly reliable, and not very expensive. The lenses are what can be expensive in the V system.
In addition, I have two Pentacon-6TL bodies, Exakta 66 MK2, Kiev 6c, Kiev 60, and a Hartblei 1006m body that takes Hasselblad backs and P6 lenses.
Those P6 lenses are not particularly expensive, and are of a most excellent quality.
-Dan, use all this stuff regularly.
