Hi everyone, Im looking to buy my first SLR camera. Im going to buy a digital, but Im between cameras right now and I was hoping I could get some insight from some of you. Right now Im looking at three cameras: Nikon D40, Nikon D80, and Pentax K10D. Right now the Pentax looks like a good deal, as I am probably going to be using it in dusty conditions (photographing off-road motor sports and nature in general), however, I am not sure as to the quality of the Pentax. also, all the cameras are coming with an 18mm-55mm lens, however, on the D40 I have the option of getting another lens as well (55mm-200mm), thus bringing the price in closer to the other cameras. I just need to know how some of you feel about the quality of all/any aspects of these cameras (also, if you think another camera close to the same price range would be better, then please let me know what it is and why). Thank you very much.
