The thing about the Nikon cameras is they seldom need service. You can buy a beater Nikkormat for $30 and it will probably work fine. I love the cameras, but don't love many of Nikon's lenses. However, w/ the availability of adapters, now I can put all sorts of lenses on my Nikon cameras. This works out great.
I think the best film bargains are all the AF cameras that can be used w/ MF lenses. My $13 N70 is a fun camera! No, it's not built to the standard of my Leicaflex, but it has a fast motorized film advance, spot, matrix and center metering, it's light and small, has a 1/4000 top shutter speed, and if it ever dies it will be $5 to $15 to replace it.
EDIT - I apologize. This should have been started with "In My Humble Opinion." My experience is a very tiny subset of all the users and all the cameras out there. But I suspect I am not the only one.
That is hogwash and pure Internet rumor. I know that I am going to upset a lot of Nikon fanboys on this forum but if you have not had to repair a Nikon camera you have been lucky. I apologise if I am offending anyone but professional cameras get used very hard. When a pro finally sold one it had already seen hundreds of thousands of shutter actuations.
It seems that whenever this comes up the first thing that accompanies the statement is "Nikkormat." Nikkormats are no different than most Pentax's, Minoltas, etc. They were intended for the consumer market. They were never intended for the professional market so it is still possible to find Nikkormats that have not been used hard.
Nikons are a different story, especially older models. I have owned three Nikon Fs, an F2, two F4s and an F6. The only one that did not require service was the F6. And that service does not come cheap. Oh, to be fair, one of the Fs required some shutter service that I was able to manage on my own so I guess you could say it did not require a trip to the technician. I have had way better luck with my Minoltas.
Even my Leicas, and I own several, have all required some form of service with the exception of my MA. It is all part of the cost of owning and using these wonderful cameras. But I have never assumed that these cameras would run without some service required.
