Leica M7 for €4200.- - well if this inexpensive for you - for me it is definitely not
That's a new camera from one of the most expensive, few film camera makers still producing film cameras. Of course it's expensive. It's also a model that came out in 2006 or so and hasn't changed since.
My intent in saying that film cameras are cheap is that many of what were once very expensive cameras (like my Leica R8) now go for effectively pennies in almost new, unused condition. I bought that R8*body which listed at about $2500 or so in 1997 for $199, in the box with all papers AND the winder attachment, practically unused all of it.
My point is that there is virtually no one making film cameras in successive new models with improvements any more, and there are darn few making high quality film cameras at all in the larger view. The Leica MP is still available and hasn't changed since it was introduced. They introduced the M-A ... which is essentially the M4-P revisited with the same viewfinder and internals as the MP. And Leica was always one of the more rational manufacturers, changing things in a measured, slow, incremental way.
A contrast to Nikon and Canon, who produced at least 20 new models each between 1980 and 2004, as well as both announced and silent updates on existing models (example: the FM2n was revised and updated, finally in major ways, three times from its release to end-of-life). I know folks who bought through about half of the new models from either looking for that small increment of improvement.
So the only reason that shooting film reduces how many new cameras you might buy has to do with the fact that there aren't any new film cameras with new feature updates to speak of anymore. Making new film cameras is over, a dead business, other than for a couple of traditionalist holdouts who produce them at very high prices for a very limited audience, and a couple of happy specialist folks who make entertaining inexpensive ones for niche market enthusiasts. However, there are thousands of excellent, once-expensive film cameras out there so if you want to get into getting the very best, the game is the same as if you buy into each successive generation of new digital camera.
I'm so glad I no longer play that game. Both my digital and film kits are quite stable now. In fact, I'm still editing them down, curating to just the select few that I use, get the results I want, or like for nostalgic purposes.
