But you can call me Steve
There was an ad for a Bessa R2 that is still up if you dig for it, it's the deal of the century if you ask me.
A leica iii costs a lot from what i see. A serviced one since we are talking about an 80 years old camera costs with a lens almost as much as a leica m2 which accepts m mount lenses and much more than a leica cl which is also a compromise( to me if someone goes to leica all in he should get one of the modern ones say after the m6 or if one doenst want lightmeter m4-p) but also accepts m lenses. For a very decent price say 200 body 150 lens id try a pretty old camera with everything fiddly on it. Dont take it negative i also really like the rollei 35 for example but the lack of rangefinder and the strange focal lenght are not things i can just swallow, especialy since film costs a lot at the time.
By the way i often visit amsterdam for some street photography so here is a photo with a pentax mx 28mm lens
You must be very lucky in that your EOS 300's film back door doesn't need any new foam replacement.Even Canon EOS 300 is more effective for little use of film, than any film M. IMO. We have it at home since 1998, it needs no service and just works.

Kodak Medallist I/II could also fit the bill. Or at least it feels similarly tank-like. Granted the cost of the film might undermine the lower cost part.
Not sure if it got any. It is plastic.You must be very lucky in that your EOS 300's film back door doesn't need any new foam replacement.
Tank-like, inexpensive, medium format rangefinder? Hah, Koni Rapid Omega 100 ;>Kodak Medallist I/II could also fit the bill. Or at least it feels similarly tank-like. Granted the cost of the film might undermine the lower cost part.
We've come a long way from the OP's cheap sturdy camera opening post....to $900 for a body....There was an ad for a Bessa R2 that is still up if you dig for it, it's the deal of the century if you ask me.
I agree.... none are cheap. I have that set-up a CL (working meter) with a Canon 28 and it's a tiny gem. But we've come a long way from the OP's "i got an F2 for $75....& not I want a cheap sturdy rangefinder." ......to a $1000 set-up. Honestly i don't think you'll find a cheap rangefinder with a 28mm.....None that are cheap. The only ones that I know of with 28 mm frame lines are from Leica M4, the Nikon SP or certain Voigtlander Bessa models that looked at as collectables these days/
I did used to have a Leica CL that you can get semi-inexpensively, especially with an inoperable meter (say $400), that I would use the whole finder window for my Canon 28/3.5. It came very close to fully coverage.
Been there done that. Is the OP asking for the impossible? I think so......You pay once, use many times.
