I shot the births of both my children on Neopan 1600 in a Nikon F3, so I have very fond memories of this film. It does still seem to be pretty freely available. It would seem an odd film to cut as I would have thought there would be a demand for it, it's not that there is a direct replacement. Delta 3200 is good, HP5 pushed to 1600 is ok, T-Max P3200 is good but in my experience (using XTOL) neopan 1600 does just have the right 'look' for the types of situations that you would use this film in, which for me is ambient light interiors. Quite contrasty but not over the top, reasonably fine grain for the speed and just the right speed that I need.
