Does your camera have any stuck pixels?

Hi Pentax Pixel Peepers! After shooting RAW exclusively for some time (and using Silkypix that virtually eliminates the problem automatically), I was alarmed to find stuck pixels when I tried some JPEGs again. I'm interested to know how common this is - particularly with the *ist DS model, but with other models as well - particularly because I am hoping to sell my camera. I don't want to put anyone off, but neither do I want to be dishonest by not mentioning it in the advert if I should. I understand that it's something that can happen with all digital cameras, and more likely to happen the older or more used they are - but to know just how common it is with Pentaxes would be useful. Please Google for more info on stuck pixels if you are not familiar with the subject. (Stuck/hot/dead pixels can also refer to LCD screens, but I'm talking about sensors). Note that hot pixels are slightly different in that they are temporary and can be gone when you use the camera again after it has cooled down. Stuck pixels are permanent. I would be greatful if you could vote in the poll. If you have a DS and another model too, please just answer for your DS. There is no "Don't Know" option in the poll. If you don't know, please either don't vote or test your camera for the problem. Stuck or hot pixels show up as bright tiny points of light against a dark background. Note that long exposures may introduce noise that complicates the issue. So I think it's best to test by taking "normal" photos with some dark areas in the background - or a not-too-long exposure in the dark or with lens cap on then pump up the levels on the computer to examine. Any other comments or advice would be interesting as well. Thanks very much.
