How do you guys get your sensors so dirty? I've had my 60d for almost a year and its fine. Just don't change lenses with the camera on, don't change lenses with your camera facing wind, keep a body cover on it, clean the back of your lenses, keep your camera body clean. This isn't rocket science.
On the note of this thread, sick edit as always. Your glide-cam work is really nice. My only comment is that I didn't love the slight-purple grading, granted I'm a photo guy so to me it just looked like your WB was way off.
