I hope your friends Skin cancer diagnosis is an early one , and it is one of the less aggressive sorts
It is quite Ok to put the camera troubles in perspective in relation to that TBH
However I agree with all that has be written above
It is not unlikely your camera was going to "break" and is therefore neither fit for purpose under the sale of good act, nor is it good business on Nikons part to feel you they can fob you off , just because they feel they have a big enough user base to lose you
It is time to put your annoyance into effort
You sell the cameras, not just to earn your keep, but your very capable use of them is unpaid advertisement for Nikon
I would like to think these Forums and you being a valued member of the community also serve that purpose
£300 to repair it so soon after purchase, and used not underwater or in the tropical rain monsoon is not funny
Neither is your account of relentlessly pursuing them ..only to get this rather lukewarm reply
I think you should make you annoyance and disgust known in a very controlled manner copying as many of their top brass as possible
I don't think fixing it gratis is going to put them out of business and in future, get names of people you speak to and times so that the remark by the girl on the phone never gets repeated if Nikon put "weatherproof" on the D3 as a selling point
Short answer: As empathetic as you feel about your Pal, do your best to make anyone in Nikon reading your letter feel uncomfortable..even if it means a subtle small claims court threat.. They can ill afford the bad publicity despite thier market share in the camera world. Disposable income is not rising and thay need all the goodwill they can get TBH
Good luck
