Looks like the DCF are discontinued.
If I have nervousness about Nikon, it's customer service.
Nikon has had quite a mixed reputation for after sales and warranty issues in the UK, so when I checked out the Monarch HG a few months back I asked what the dealer thought of the current service. He said Nikon had some fairly rigid rules but he was quite happy with their support. On the other hand, he wouldn't touch a Leica.
I think you've probably realised now that the old Nikon HG was a high end alternative to the field flattened EDG, and totally different from the current Monarch HG.
