I am inspecting a new 70-200mm VRII and see a noticeable speck of dust behind the front element. It is big enough for me to easily see it without even having to shine a flashlight down the lens. I understand that dust will inevitably find its way into all lenses, but I do have the option of exchanging for a new one. I don't have OCD, but I feel a bit of pain accepting a $2100 purchase knowing that it has imperfections on Day 1.
Brian, I respectfully disagree that a brand new lens should have "a lot of dust in it." After a few years, sure, but not fresh from the factory. Maybe a little dust is okay, but my tolerance for dust is inversely proportional to the price I paid for the lens.
But that's a different argument than "it affects resale value" since presumably it is a rare circumstance that you'll care about resale value a month or two after you buy it.
As far as "lots of dust" there are an average of about 100,000 dust particles per cubic foot in average indoor air. I don't know how a lens that is outside of a clean room (ie bunny suits etc) is NOT going to have 100 dust particles inside the lens.

If no-one was willing to buy a used lens that had some dust in it, the second-hand market for lenses would collapse...! I don't think I've ever bought - or sold - a used lens that was completely dust-free, nor would I expect to.
I was in your shoes with the same dilemma half a year ago, except the price tag was $2,400 back then.
After my wallet became so much thinner, I was thrilled to welcome my new 70-200mm 2.8G VRII home. However, half an hour later, I was disgusted when I looked down the front element and found some specks of dust inside. Without flash light, I could see some. With flash light, a lot more became apparent. I posted my 1st post on this forum for that. I couldn't get any helpful response. So I started a quest to check out as many brand new copies of this lens as possible. It turned out every single brand spanking new copy of this lens I could find had more or less specks of dust inside.
Having said that, there were a couple of responses that stated there was no dust in theirs. However, the "dust free" copies appeared to be the minority, even if that was indeed the case. There was no way for me to confirm those responses were true or not.
So I settled down and started examine the images taken by this lens very very carefully. I couldn't find any evidence of the dust in my images. Not only that, this lens quickly became my go-to lens for pretty much everything, with the side benefit of helping me with weight-lifting exercise every time I brought it out with me.
If I could give you any advice, that would be to check out other brand new copies of this lens and compare with yours. I can't see inside your lens. So only you can compare and make sure yours is comparable with others. If you are still not sure, take a pic of a perfectly white background. If there is any effect from the dust, it should show up.
>I am inspecting a new 70-200mm VRII and see a noticeable speck of dust behind the front element...What would you guys do?
Exchange it for a new lens. I want to be the one who puts ALL the dust in my lenses.
I always inspect a lens before I buy. (I buy new Nikkor lenses only from a brick-and-mortar authorized dealer.) Any defects I can see are cause for rejection.
That being said, I own a Nikkor 50mm f/1.4 non-AI from 1971, and have never seen any dust in it. Come to think of it, I've never seen dust inside any of my Nikkor lenses. Lots of dust and stuff on the outside that gets blows off.

Here is a perspective. I recently spoke at length with a pro. He was shooting an FX body with a Nikon 70-200mm. The lens looked like it had gone to battle. Literally dented, dinged, scratched, marred, and well worn all over. But it was producing fine images, images that passed scrutiny and made him money. I too have worried about a speck of dust in my Nikon 70-200 VRII. But after speaking and watching this pro, I felt like I was someone living in a bubble and more worried about keeping my gear pristine than, well, shooting images! Go out and shoot that new 70-200mm VRII lens of yours - you'll love it.
