Return of the prodigal camera - D600 and dust spots

My D600 just came back from its second trip to Nikon repair for excessive dust spotting on the sensor.

If you look at the invoice the following parts were replaced: shutter mechanism, aperature operation, memory compression, and a lot of other things were checked and cleaned -- all for free as part of the warranty.

Now let's see if it does the job. I'll report back once I've run sufficient tests.
