I had an S2a for a long time with all the interesting accessories and lenses from 40mm to 500mm. You can put together an extensive system fairly inexpensively, if that's of interest.
Particular attractions of the S2a:
Nice and mostly affordable selection of Nikkor, Zenzanon, Komura and other lenses.
Very easy to adapt large format and historic lenses thanks to separate focusing helical or bellows, shutter, and lens and secondary screw-mount option in addition to Bronica bayonet.
Availability of a tilt-shift bellows for macro and tabletop work.
Switchable 12/24 backs.
I sold it after I built a Linhof 6x9 system, and decided that I didn't need two whole medium format systems, though one was an SLR and the other a rangefinder/technical camera.
