As-per the topic, I'm considering a rangefinder (instead of getting into MF). I know the Leica M2 has frame lines for a 35mm lens, but that is about it. Are there any other m-mount cameras that have wider ones? In addition to TTL metering? Auto-exposure isn't a must, but I wouldn't mind aperature priority.

I do plan on getting a light meter in the future, but TTL would still be more help (eg. allow me to carry less if I'm running around somewhere).
