Have you tried out the Fuji X100 and its later iterations? Yes, it's autofocus or electronic "manual" focus with a faux-coincident rangefinder mode and a fixed lens, but it's about 1/10th the price of a digital M-series Leica and lens. I've had an X100S for almost nine years and still use it daily. I really like how compact it is and I feel like I've learned through practice how to anticipate moving subjects and compose decently well with the frame lines in the optical viewfinder.

Yep, I owned one of those for some time.

Definitely the best one so far, but still not even close.

I don't want any gizmos, just great optics in a solid rangefinder body with a non-toy optical viewfinder, large sensor and convenient controls.
