Hasselblad 500CM kits with a Planar C (add a lens hood for flare protection) are quite reasonable in BGN condition from KEH. Check prices again I say.
Otherwise, you can get an East German Pentacon Six with a Carl Zeiss Jena Biometer 80/2.8 lens - not quite a Planar but it's a pretty decent lens and significantly cheaper than a Hasselblad system.
The 80/3.5 lens on the Minolta Autocord is also excellent, certainly almost on par with the Zeiss lenses on the more expensive Rolleiflexes.
Another shout out for the Bronica SQ-AI with 80/2.8 Zenzanon. A friend uses one and I've never been able to distinguish any differences in quality between his photos and mine shot with a Planar.
