BTW - I insist, R Leicas, except for Leicaflex, which by now is better left alone, as it is not serviceable at reasonable cost anymore, are better left on the shelf.
"Reasonable cost" different people might have different thresholds of what is reasonable, depending on how much they enjoyed using the camera.
I recently had Sherry Krauter do a CLA, battery box repair, and recalibration of the meter to be accurate with currently available, i.e. legal, batteries and it cost me around $300, which means I've got an SL2 with accurate shutter speeds, accurate metering, and a nicer viewfinder than the one in my F6, with about $500 total invested in the camera, and it's a jewel. Is my F6 a better camera than the SL2? Other than the fact that the matrix metering on the F6 tends to be somewhat better in difficult lighting situations, no, it's not.
Since Leicaflexes have no electronics except for the meter, and will work perfectly well even if the meter failed completely, and are built to extremely high standards, I can't see any reason for it to be more prone to failure than an M3, and people aren't keeping those on a shelf. It's a shutter in a box, there's just not much that is going to go wrong with an SL or SL2, doesn't seem to me.
Plus, there's that whole feeling some of us have that it's just nicer to use lenses on the bodies they were made for, everything just works. But, that's another thread.
To each his own, and I'd agree about being nervous about R bodies, but Leicaflexes are a joy, at least they have been for me. Odds are very strong that I will die before those bodies. But, I'm old.
