You're welcome!
The results can still be disappointing, due to the film curvature
(a compromise focus, with small aperture can help). Duping films
aren't very sharp, alas - and standard films are too contrasty for
duping.

I don't know of others (logical as their existence would be...;-),
but a call to B & H and/or Nikon (1-800-NIKONUS) should tell you
if they are current (let me know).
