It's just amazing... So many people are asking which projector to buy 'which is best?' they ask. Then they list off the models - Z4, AE900, HD72, IN76... I just tell them to flip a coin. There doesn't seem to be one that can really be called the best anymore. They are all awesome. The $10,000+ Sharp Z9000 of a few years ago basically produces a worse image than the currently crop of $2Kish HD projectors from both the LCD and DLP camps.
I personally have seen the AE900 and love the ease of installation, but will be seeing my first Z4 in a week or so. Bottom line is that I thought the AE900 was a little soft and with where the viewers are seated in this theater the Z4 should be ideal. I'm very excited to see it.
Great review, and it seems to show a bit of difference in attitude towards that projector after you guys having seen it set up poorly at some trade shows, etc. may have led people to believe that the projector was a good deal less than top notch - while other sites are claiming it to be the best of that price range.
Want a $2K projector? Pick one of them, it is almost impossible to go wrong.
