I was told months ago that the reason that particular Nikon eyecup was hard to get was because it was discontinued. I put mine on a wish list from B&H Photo in New York over 5 months ago - still have not heard anything back from them. So it appears as if what I was told is true. There are some intermittent stocks to be found across the country, but they may be in the most unlikeliest of places.
Now if anyone knows of a place where they are still available... please share this with us as soon as possible.
Now please, don't list a location in Baghdad or Asrha, or places like that. If that is the case, then I'll have to contact one of my photographer friends in the Marines who will look out for it once the offensive begins!!!
