Does it have to be an autofocus model?
I have an XE-7 and that thing is SWEET. I think the only thing quieter than an XE-7 is a camera with a leaf shutter. Film advance is dead silent, silky smooth, and the shutter/mirror is very quiet for an SLR. Shutter's actually a Leitz / Minolta collaboration, from back when that actually meant something.
Full info viewfinder (sans film speed) through little optical windows that show the aperture and shutter speed. Pretty cool.
Little window right above the exposure counter that tells you if the film is properly loaded in a tactful way (little red square). Yeah, I've had to use it....
Aperture priority for the decisive moments.
Hell of a camera for the mid-70s.
