(Waist level finders for MF)
The answer is usually supply and demand, but why? For auxiliary finders for rangefinders, I sort of understand it. The aux finders get separated from their lenses / cameras easily and may get lost, so the supply diminishes, and the RF market has long has a collector's influence and limited supply. But there are substitutes for shoe-mount viewfinders.
I've posted a couple of times about the recent high prices of waist level finders. As far as I know, this is a relatively recent phenomenon, like past few years film revival. As you say, some MF cameras were originally used with prisms and not WLFs, so the supply is partially limited. This is especially true of 645 SLRs, where the WLF is awkward for verticals, but less true of 6x6. The odd thing is that WLFs of course were originally much cheaper than the prisms, but now prices are inverted. I understand why WLFs for 645 cameras were rare to begin with, but I understand less for WLFs for 6x6 and the RB67.
So why is demand higher? I think the iconic nature of the WLF on a medium format camera, especially the Hasselblad - it's what people picture when they think of an MF SLR, and that probably appeals to users in the film-revival crowd. Plus it's lighter than a prism and doesn't have issues with mirror coating going bad.
Because a bunch of the bodies that are still in working condition were sold with an eye-level finder only.
Most pros doing wedding work and the like tried to avoid the dreaded "navel eyed" view of the world.
