Summary: I bought the PT-AE2000U one month ago, July 2008. It has surpassed by expectations. For the price I doubt you can find better. The start up time is under 1 min. The picture resolution is very good with Time Warner DVR box using HDMI and fantastic with Blu-Ray. The box is quiet and not hot during operation. The set up is a breeze. Autofocus works well. I have used it during the day many times when the ambient light is not well controlled and the picture remains good.
Summary: I am a die-hard CRT fan, but I finally had to buy a new projector to handle 1080p sources. I have never seen a fixed-pixel projector that can compete with CRT on black levels and shadow detail, but as CRTs are basically no longer produced I had little choice. I purchased the PT-AE2000U instead of the Sony VPL-VW60 principally due to the lower price of this projector.
Summary: Excellent price performance. You can find a better projector but it costs more than 2X before you can see some different. For most consumers, this is an excellent projector, great colors out of the box, reasonable sharp, lot of settings can be tweaked, very quiet fan. The black is not as good as JVC RS2 (one of the best projectors) but it is good enough for most people. The project must be watched in the light controlled room or the colors will be wash-out.
Summary: Personal Experience I have had 4 HD projectors over the past 5 years. Each one stepping up in quality. My last was the HC 3000 Mitsubishi Projector DLP. The quality of the Panasonic 2000 is incredible. I do find myself wanting to fine tune the image often when I change video sources etc. Might just be user error. I did have a problem with the image on black screens. I had the projector in my possesion for 15 days before I decided to send it off for service.
