The register distance of Nikon is larger than that of EF, so building an adpater
that maintains infinity-focus without an additional optical element is no problem.
I haven't bought an Nik2EF-Adapter, but an Adaptall-2 to EF Adapter from a
chinese seller in ebay ... they sent via registered mail, but posting can take up to
3 weeks. Nevertheless, they deliver quite reliably. (It's the second item I bought there).
Regarding AF-confirm ... I don't know if its really worth it ... I do get good results
with an adapter without chip and an EE-S focussing screen in a 5D ... nevertheless,
the seller I bought from, has also an adapter with AF-confirm chip on it, and that is
still well under 30euros (including shipping).
The seller goes under the name "jeanz-sh" in ebay.
Regarding build quality ... I can't speak for the Nikon2EF that you need, but the one
I bought is well crafted (I mean you really don't expect much more than being machined
exact) and fits to lens and camera just right.
just my 2 cts ... Rainer
