I guess the real question is, How bad is it? I have a couple of hot or stuck pixels in my D300. They showed up well after the warranty was up and I'm not willing to pay what it costs to get them mapped out of the sensor.
Since I know where they are, I can always find them, but they only really show up in dark backgrounds areas and they're easy to fix in post. With all the millions of pixels in an image, when you print the image do they really show up? Most of the time I ignore them. sometimes when they're obvious I simply clone them out of the image. I don't consider it a big deal, and I probably wouldn't return a used camera because of it.
It is simply part-and-parcel of using digital cameras.
