Yes, Nikkormats are around 20-25 dollars these days.
Talk about an underrated body.
It really is insane how little they cost. With those four bills, one could get Nikkormat with a lens or two, a CLA (though probably not needed), and an incident light meter...and be so much better off in terms of exposure to boot.
I got my outstanding-condition F Photomic T with three cased lenses with hoods (35mm f/2.0, 50mm f/1.4, 135mm f/3.5), original cased and boxed Nikon filters, and proper Nikon cable release for $350 from Photo dot net classifieds. I added a 24mm f/2.8 lens from E-Bay for $50, near mint. I added my black F Photomic FTn to the kit for $140 from a pawn shop. Then I got a Nikkormat with three lenses (50mm f/1.4, and Vivitar 28mm and 135mm f.2.8), an enlarger with a Schneider lens, a Yashica D, and an old leather case full of Zeiss film/plate holders and filters, all for $100 at an estate sale. I sold the 50mm lens for $40 and the Yashica D for $25. The Vivitar lenses and Zeiss holders have proved harder to sell, but in the end I think I will actually make more than $100 from selling the unneeded stuff from the lot. So, in the end, I have a four lens, three body professional-quality SLR kit and the enlarger to print the film for $575 (plus two Vivitar lenses and some Zeiss holders, which will be sold eventually). Crazy! And none of these cameras have ever failed me in any way or needed any type of service performed or expenditures on batteries. In light of this, yes, I would say that 4 bills is quite out of hand for a later amateur body alone.
