Admittedly, I'm a bit biased, but one thing to keep in mind concerning LCD projection systems is that over time, not only does the bulb, but also the LCD panel iteself begins to degrade. Over time the image quality (in particular color saturation) will worsen, and the only thing to be done is to replace the LCD panel. In contrast, with DLP technology, when the bulb is replaced, the image is as good as the day you bought the set.
