The shutter failed in my Nikon D3 last weekend while shooting a wedding in the Hamptons (I'm Atlanta-based). So I sent it off to Nikon last Tuesday via FedEx. They got it on Thursday morning, inspected it and estimated the repair within two hours ($420). I paid online late on Thursday night. It was in the shop on Friday and shipped on Monday. I got it today (Thursday). 2 days in house and 7 business days total.
It arrived with a replaced shutter, replaced LCD window (which I did not ask for, but it was fogging), replaced rubber throughout, replaced card cover, and a full clean and check.
I know that NPS gets a lot of flack but this has been pretty typical service every time I've sent gear to Melville. Thoroughly impressed again. (bv)
