I am looking to buy a used D600 as my first full frame... this is a picture of the sensor... is this normal?

That’s not the sensor, that’s a photo of the mirror reflecting the focus screen, which is illuminated by light coming through the viewfinder.
To see the sensor, the mirror has to be locked up, and the shutter opened. It’s opaque and often greenish due to the color filter array.

Ok thank you!!

Be careful poking around inside the camera, as there's the danger of dust particles. Change lenses in clean areas away from breezes, and avoid hand-operated blowers.
Inexpert efforts at cleaning the sensor, mirror, and VF screen usually end in tears. There's a sensor self-cleaning option on most Nikons (buzzes the sensor at start-up).
Check for sensor dust by shooting the sky at f/16. Dust on lens surfaces doesn't usually cause a problem, as it's almost always out of focus for the shot.

I've seen many people on these fora recommend using a Giottos Rocket Blower. First I've heard that is a bad idea.

Blowers redistribute dust, and this might be OK for some purposes, but you never know where it will end up if you puff around in the camera's vital bits.

The rule I was taught was that if you need to use a rocket blower for your sensor to clean off some dust, was that you blow it while holding the lens mount facing down so that there's a good chance that any dust kicked up exists the camera's innards and gravity takes over.
But as emphasized...clean it when you need to clean it. As in you see specks on your photos at higher F-stops. If the "clean sensor" doesn't work, then try a rocket blower with lens mount facing down. If that doesn't work then do a wet-clean.

You are UNDERVALUATING your advice @ only .02 ...
It is worth at least DOUBLE that, (heck, maybe even "triple) !!!

Quite probably back where it started from . . .
. . . on your sensor.
I've always avoided blowers like the plague.
That idea gets a lot of support in some quarters although I've never really understood how that might work.
Have you ever tried to pour dust . . . ?

The few times I've had dust on my sensor that the auto sensor cleaning couldn't dislodge, the blower worked fine with a few puffs with the lens mount pointed down--dust particles were gone. YMMV of course. I have no clue where the dust went, but it as no longer on my sensor--and if it hung around in my camera it would be months before it showed up again.
As for the "lens mount down", it might not do anything, but it seems logical. While you can't pour dust it's still affected by gravity--even if air currents dominate dust's motion when loose. It might do nothing, but it also might up the odds hat the dust leave the camera body as opposed to floating slowly back down onto the sensor.
The proof of course is whether or not the dust is off the sensor, and for how long.
I do think that in any case if you have the automatic sensor cleaning set up to do it upon powering on/off you should be fine. There's no reason to regularly blow out your sensor "just in case" It's like cleaning the front element of a lens...you do it only when you need to do it. If you don't see any dust specs, don't bother.
In the case of you an Wrycuda: what would either of you suggest if a beginner has dust on their sensor that doesn't warrant a wet clean or sending it back in?
