I haven't needed to clean the D600 yet, but I suspect that I will in the near future. Here is my situation. I have a local authorized Nikon shop that does cleanings while you wait, and that's what I have always done. I have never cleaned the sensor myself on any of my other cameras. Should I just continue to use them, or should I start cleaning the sensor myself? If so, which kit? Basic Kit w/SensorView or SensorSweep (I'm looking at Copper Hill Images site)?
