Is a Shutter count of 30, 371 too much on a Nikon D300?

I'm interested in buying this camera but i'm not sure what to look for wen buying used.

Not at all. I can shoot that much in 2 weeks.

Just broken in! It still has years of life left in her. Look at the body. Any damage? Nicks, dents? I saw one on e bay where someone had painted their name on the side of the camera!
Aways best to buy from a seller who can give you at least a 90 day warranty.

Yup, I do that in a couple of months as well. I've seen D300's and D700s w/ as many as 300K so you have lots of clicking left.

No, that's fine. Only thing that can happen by then is some of the grip rubber letting go but that's easily fixed

Given that an estimated 94.4% of the D300 shutters still work after 31, 652 to 70, 239 clicks, you should be alright, especially so since a very respectable 39.1% are estimated to keep on working after 3, 780, 118 to 8, 388, 607 clicks (see link below).

This is virtually as good a score as Nikon's previous top-of-the-line D3 series and substantially better than for instance, Canon's 5D.

If I was considering a D300 and this particular one was offered at a reasonable price, I'd certainly go for it. You'd probably run a higher risk of camera failure by dropping it than a defective shutter for the next 500, 000 clicks or so.
