I am new to the forum and I am considering purchasing a new projector. I have never actually seen first-hand a demonstration of a D-ILA projector. What is it's achilles heel? What is the down side to this type of projector other than noise or the heat output or having to replace the bulb? What does the image look like compared to a high quality CRT front projector? Does it not do well with certain types of images e.g. fast motion. How does it do with blacks? Does it have to be calibrated frequently? I know that it's very bright compared to a CRT projector. It's hard to put down that much money sight unseen.
