I asked myself the same 500 vs 2000 question and consulting with a Hasselblad repair tech brought the answer very fast : the metallic sheet focal shutters of the 2000 series hasselblad cameras may be relatively resilient, but if a failure occurs, then you're in trouble, because space parts are generally no longer available, so you have to canibalize another body to repair your broken camera...

The 200s, with cloth shutters on the other hand are much better, and like other focal plane hasselblads, allow for the use of wide apperture lenses like the 50 f2.8, 110 f2.0 and 150 f2.8, as well as the Russian Kiev lenses that can be adapted. Those lenses are not cheap, in general...

The basin Hasselblad workhorse is still the 500C/M, and you can upgrade later if need be...

(as for bronica vs hasselblad, I'll place my vote on the swedish cubes any day...)
