I'm looking for a compact medium format RF.
I'd prefer it to be mechanical (but not a deal breaker) and I do not need a meter or interchangeable lenses.

Originally, I narrowed it down to these three cameras:
-Makina 67
-Bessa III (GF670)
-Fuji GS645

But I would perhaps consider these two:
-Bronica RF645
-Mamiya 6

I'm not really interested in these cameras:
-GA645: I want manual focus
-Mamiya 7: I'd rather get a 6 because it is more compact and 6x6 (my preferred format)
-Classic Folders: too unergonomic
-Fuji 6x7/6x9: too large

Well I'm not so concerned about lens quality, lens speed, and negative size but mostly the reliability and useability.

-How do these cameras compare in reliability/durability? I like the compactness of the Makina and Fuji GS645 but I fear that they are not that reliable and durable. I plan on "throwing" this camera in my bag without hesitation.
-viewfinder/rangefinder: can I assume that they re all good enough?

Well I'm really interested in the Makina but I fear that it is too expensive (6x7 and an f2.8 lens commands $$$) so the Fuji GS645 is a good alternative given that I can accept 645 and an f3.4 lens. But then I fear that these cameras are not that reliable so perhaps I should just get a Mamiya 6 since it is probably cheaper than the Makina, more reliable, easier to find, and just more practical at the expense of bulk.
