Do you think that the following is a good deal? 

Depends on what you want to do with it.  While I think a D3 might make a good boat anchor, $3,388 is too much if that's all you need.

Just kidding, of course, as I'd love to own a D3 (for taking photographs).  I can't help with the price, though.

I want to use it for Sport, landscape, event and portrait and macro photography. 

The D3 is obviously a great camera as far as quality, but one thing gives me pause.  If you are using this for sailing pictures, landscapes and other outdoorsy photography you may find that the weight becomes an issue.  Lugging around a heavy camera can be limiting depending on what you are doing and what your fitness/strength level may be.  You might consider a lighter camera instead, such as the D700 (5 FPS) the D7000 (6 FPS) or even the older D300 (6FPS).  In daylight, all of these cameras will give you similar quality, honestly.  The D3 will dominate in low light situations, followed by the D700, D7000 and D300, but is that your deciding factor?  I use ISO 3200 on my D7000 regularly and of course the use of flash indoors makes that unnecessary.  Choosing one of these less expensive bodies would allow you to spend more on lenses, and that could make more difference as far as your images.  It all depends on what kind of use you have in mind for the camera.

I bought my D3 2 years ago with 65 000 clicks on the clock. Paid £1699 for the body. Serves me well, especially in low light for people photography. Ergonomics great. Heavy, and carrying it around becomes a drag, especially with those FF Nikon lenses. I miss the Sensor cleaning facility, but have lately started to clean it myself. A real work-horse, and indestructible. However, given the size etc, I wonder if a D700 won't be more suitable for the work that you do? I don't that there will be much difference in the image quality, even when pushed, or in low light.

Im 23 years old, so I like to think my strength is good, haha. 

Wise decision!

Hi Christian,

We bougth our D3 used at eBay with 2000 and 8000 clicks, mint condition. In Germany.

I have borrowed and used the D3 (and D3s) a bit, and like it a lot!

There is always a risk of being stopped. But if you show the customs it has shot thousands of frames, most of them would consider you an already heavy user of the camera, some kind of addict probably. Remember, most people used to at least two Christmas celebrations on a 36 frames film.. 

Yes there is indeed. I have bought most of my gear in the EU while visiting family (prices are lower, and I can get the VAT back), and brought it into Norway. Most of the gear was below the exemption limit, so it was legal to import duty-free. Once the gear was in Norway, I've filled out an "identification form" (incl. model and serial numbers) and had it stamped by Norwegian customs. I take those documents with me when travelling.

Yes, I've used it when I've been traveling with lots of new looking gear. Otherwise I never care

I am using it, just in case. Very easy. Just fill it out, take your gear with you and you'll get a stamp. The two times I've done so, they even did not check the stuff and just signed and stamped.

Is there VAT on second-hand goods bought from a private individual? I don't think so.

Correct, there is no VAT for second-hand goods bought between two private individuals within the country. 

Yes, you live in Bergen..

Sure. But you can have it done at the airport, just when you're travelling with the equipment abroad. The two times I have done it, it took less than 5 mins.

I've done that, then at later travels they told me I had to go to some office, which I never did. I have also made my own lists and getting them stamped at the airport.

The camera is located in Denmark close to where I live, so no problem with VAT. But thank you all for thinking about it and pointing it out:)

That is a very good price!

Great, I will go out and look at the D3 today.
