50/mo is mightily impressive, considering that I'm sure most people who would be inclined to use them would have bought them when they were recently released...
Shame about the -A models, though. Maybe too much to hope that they have a new replacement coming out soon, heh? I think the mechanical stuff being preferred is likely a big factor in their discontinuation (along with the ZI shared(?) shutter parts). Enough time has gone by that people have realized that dead electronics often mean dead cameras (shortage of irreplaceable parts like microchips or circuit boards). That's one of the big reasons that the mechanical cameras enjoy the faith people put in them. For example, (I'm not saying that the FE2 isn't a great camera, but) FM2s cost considerably more than their counterparts because they're fixable. If an FE2 dies from an electrical gremlin, it's not cost-effective to fix.
The younger generation has realized this from growing up with digital stuff and understand that most stuff that requires specialized circuitry has turned into a case of "throw away and replace," which is why despite the newer/final generation of AF film cameras (or most cameras that require a battery for more than just powering the meter) are now insanely cheap and crazy bargains compared to their prices when released originally. My friend and I were recently comparing depreciation, and laughing at how both of our AF film cameras (my N80 and his EOS 500n) had depreciated to virtually nothing. I forget the numbers, but he bought his camera body for $10 , compared to costing roughly $800 in modern-day USD, whereas my N80 body was $30 and cost about $900 in 2013 equivalent dollars. I haven't done a comparisons or my FM2n, but I can't imagine it possibly being less than 1/80(!!!!) of it's original purchase price. Nor have I considered depreciation on my Leica/'Blad equipment (which admittedly is steep and both were insanely expensive when new, but both have likely retained a larger proportion of their value).
