Costco also have it available online bit cheaper than Tigerdirect. There are many online Forums and reviews on Benq W500. You can get more details from there. From what i have read and heard, W500 is an great projector. No one is really having any issues compared to Panasonic or many other companies. Sony on the other hand is a dim projector. So if you are planning to use it for a screen over 100', it's not recommended plus you have to have completely dark room for it. I would personally go with Benq. It is very bright, have HQV processor and 6th generation LCD panel. All the reviews are positive. PE 7700 is an older model and has lower specs than the W500. I'm ordering W500 as well next month once my room is complete. I bought a 106" Fixed Frame 1.2 Gain white screen from eastporters.
