I can see a small spot of dust or dirt when looking through the viewfinder of my brand new D7000. It does not appear on images, but it is a nuisance. Obviously it is someplace besides the sensor. Before I try cleaning anything, I thought I would ask for advice here. Any suggestions?
The next obvious place to look for the speck is on the mirror. Use a rocket blower on the mirror to see it that helps. Keep the camera tilted down while blowing - that allows gravity to pull the dirt out of the camera to the outside.

If this is your first DSLR, then get used to dirt and dust.
On the focus screen.
On the mirror.
And worst of all.... on the sensor.
Dirt/dust and DSLRs are mutually attracted to each other. It's a fact of life. Maintaining a thorough and rigorous cleaning regimen will now be a part of your normal constitutions.
I hate when people ask me what I see myself doing in 5 years...... I don't have 2020 vision!
I have owned several DSLRs, and I have cleaned the sensors many times. Like others, I've even had some cameras with dust on the sensors brand new right out of the box. I guess I have been lucky not to have anything on the mirror or focus screen that I could see in the viewfinder before. It sure was a lot easier to clean than a sensor though.
I have a professional photographer friend who has never cleaned a sensor. He takes his bodies to the local Nikon dealer before shoots, and they clean them for him at no charge.
If you see sharply defined (in focus) specks/spots in the viewfinder, they are not on the mirror; they are on the focusing screen. Debris on the mirror would have to be much larger than dust specks to see them, and they will be "fuzzy" (out of focus) if you do.
