It's also a matter of what survives near you of the old film ecosystem: reasonably-priced film, processing/scanning/printing. That it's collapsed in many places is hardly news. Still, there's mail-order for film material and possibly local/home processing leaving scanning up to you. I did see today that the Film Photography Podcast group is offering Kentmere 120 b&w at $5/roll. Probably necessary to shift to survivalist mode now--get 120 processed wherever and DIY DSLR/flatbed scan negs.
I'm looking at my nice Bronica SQ-B, Mamiya RB67 Pro S, and Mamiya 645 Super kits that deserve exercise. My plan for 2023 is to endure processing costs and DSLR scan b&w negs only. 120 color is a lost cause next to digital but I perversely adore scanned 120 b&w.
The only active market for MF gear seems to be Japan.Look at their prices. Unless you really need to liquidate, hold your MF kits and try adapting to the(somewhat unfortunate)realities of 2023. Don't throw inthe towel just yet. Good luck!
