Too bad about the trouble you've seen with the D600. I would take heart from the general silence of the blogosphere on this issue. I had a somewhat similar experience a few years ago when I bought a D90 specifically to have a light camera for a European trip (similarly remote from Nikon repair centers) that would involve a lot of walking as well as some air hops on planes with 15kg luggage limits. I gave myself three months to familiarize with the camera but, with the camera only several weeks new, the rear display simply stopped working. Still great pics but no preview and no access to menus. Luckily I had about a month before leaving and sent it off to Nikon Melville directly. I received the camera back with a little over a week to spare and, in an act of faith and hubris, took it on the trip. It functioned flawlessly and the magic is still working, three years and >15k actuations later. There's hope.
