First, I'd stay away from the Kiev and Pentacon stuff. Much better, more reliable stuff available.

If you want something fast-handling and more 35mm-like for PJ-ish shooting, then look at the 645 options, e.g., Mamiya 645(Super/Pro/ProTL bodies--skip the old metal bodies), Pentax 645(N), Bronica ETRS(i). Good glass for all and very affordable system cameras.
