This forum was very helpful for me in deciding between the JVC D-ILA and the G90. At the time the Sharp did not exist. I think that you can not go wrong with either product. It all depends on your requirements. The G90 is an awesome projector and will provide you the best picture in the 25k - 35k price range. However there were some major factors which made me turn away from it. The major factor was the size of the screen you are limited to. The advice from forum members, sales people, trade magazines, consultants etc. say do not have a screen wider than 84 inches (using a 16x9 ratio). Based on my room size and my desire to have a large screen the D-ILA was the best choice. I have an 11 foot screen ( 8 - 11 ft is the sweet spot for the D-ILA) and with my Rock+, Greyhawk screen I have created what I was looking for which is the "wow factor". You should know that the DILA G15/G20 actually improve in quality as you start projecting on a larger screen (8-11 ft wide). For me, size and picture quality were the paramount requirements. With the additions of an anamorphic lens and SDI input; I am looking to get close to the quality of what the G90 can project on a 7 ft. screen. Understand I said close. I agree with people who say that that a 9 inch CRT is the ultimate--just do not forget the smaller screen size. In fact my 42 inch plasma may be better in picture quality than all of these. BTW, the money I saved on the G15 allowed me to afford a plasma.
Regarding the sharp, I have not seen it and I am not sure how many people have really done a real good face off. Here are some of the specs:
Sharp:
Resolution: 1280/720
Lumens: 800
JVC:
Resolution: 1365x1024 (with anamorphic Lens)
Lumens: 1500
Someone who has done a face off would be better off commenting on wether this makes a difference. If you were to do a face off - I would look at the JVC on a greyhawk screen from Stewart. I am not sure I would recommend this screen with the Sharp because of the low lumens. The best test is to go check them out and decide what you like best.
Regarding noise and anamorphic lens on the JVC. I set up the projector with hush box and scaler with no problem. I do not anticipate problems with installing an anamorphic lens which I have on order. Do not let the D-ILA set up scare you away. If you think that is complicated you do not want to get into a CRT.
I would never attempt to install a G90 myself. I don't even think I could lift it to attach to the ceiling. You need two people. You also need a professional to calibrate it once it is installed.
Although the D-ILA is a more challenging install than the Sharp; it is no way close to the challenge of installing a CRT.
Finally, I would just recommend that before you make your decision you owe it to yourself to check out the D-ILA, anamorphic lens, good scaler, and a 9 - 11 ft. greyhawk screen. Then compare the Sharp and the G90 and make your decision. Do not let all the well intentioned advice you get on this forum make your decision for you. Let it narrow your decision. In the end, you need to make the decision based on your room, screen size, picture quality, and ease of use/install requirements.
