Just curious why you haven't considered the Mamiya 645...not the newer Super/Pro/ProTL etc but just a 645 or 1000s. These are in the same price range, there are a lot more of them out there, this is pretty much my main MF set up now, using WL finder, and a 55, 80 and 210 glass - which was very nice and cost was low.

Just another option...though I also use a Bessa folder when I don't want to 'lug' equipment around.
