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.
i have a few rolls of blank photos, from forgetting to load the film, or it not taking up on the spool.
the blank ones i enjoy the best because the film always looks good
