Hi Paul,
Nice to meet you at the show. IMHO, if you want quiet, the field is quite crowded with really good contenders, from those teeny, tiny 2 pound DLPs to LCDs to the new DS-1 D-ILA. The DS-1 could compete in the "sub $10K quiet" category, and would surely win the "screen door" sub-category, but I'm quite sure that it would lose out big time to the Sanyo units on the contrast.
On the other hand, the JVC G15 competes in the "sub $10K non-quiet" category and cleans up on image quality across the board, from screen door to color accuracy, uniformity to contrast...but then some people care more about a quiet projector than picture quality, so I guess you choose your battles.
If you don't like those choices, there is a new "over $10K quiet" contender - the JVC G150HT. It has the D-ILA picture, and is even quiet! However, now the price tag is a factor to consider (~$18K). Hmm...
There is no clear cut choice. There are good, better, and best projectors in different categories, at different price points.
That is what keeps this forum so active! If there was ONE projector that cleaned up on everything, there really wouldn't be much to talk about!
