Special Nikon pro shops?
Depends where your friend is situated,
Its not new, there are already Exclusive Nikon shops.
I've bought all of my Nikon gear from there,
Yes its more expensive then Jessops, Amazon, ect.
but the customer service I received was second to none.
You are treated like a valued customer, unlike the large chain stores.
They are not interested if you are just getting a D70 or a D4 with a nice 300 f2.8
You are one and the same.
Also they tend to know exactly what they are talking about, and if you want to try a specific body and lens combo then they normally oblige.
Go for it,
