I keep wanting to get an M4-2 or P but I was "let down" by a malfunctioning Leica, and I keep thinking "fool me once".. but I'm the fool to be fooled twice.

I would also consider a Hasselblad swc. Interestingly my bought new Hasselblad let me down this fall... the main-spring died in the 80, and I have a blank roll of "nice photos". Oh well... it's fixed and good to go another 2 decades.
