I have fond memories of the N2000. I used it in documentation for a professional certification. Lots of macro shots with a ring flash using E-6 film. Never failed me despite having a crack near the viewfinder.
Biggest issue in the used market is corrosion in the battery box. I remember crusing pawnshops years ago and seeing some N2000s with corrosion. Can't leave dry cell batteries forever. The Nikon manual is clear about that risk.
Great 1980s shutter sound...and the fact you need to turn off the camera. I do not recall it having a battery-saver shut off.
