I think the distinction is that the camera worked well for me... :-)
The Nikon F, Leicaflex SLs and R8, Leica M4-2 and CL, Hasselblad 500CM and SWC, and Voigtländer Perkeo II prove very hard to let go of. Same goes for the Olympus E-1, Ricoh GXR, Leica X2, and Olympus E-PL1. And all the Polaroids!
Sadly, I would really like to acquire a Nikon F6 as well. Sadly because the amount I'd likely use it is probably measured best in number of exposures per year. It would be more sensible to get a D700 or D750. Oh, the tugs of desire!
