Agreed, get one and roll with it. If you have a defective unit, get it exchanged. Remember that very few production units have real defects. When you visit a site like this, you are reading the nitpicking of hypercritical home theater buffs. You don't get to read the posts of the 99% happy buyers. You read the bitching and complaining of the 1% unsatisfied. This type of forum will skew perception and scare people. Don't let it happen to you. Back when I was building my theater a couple of years ago, I was considering the Epson 8500 but I was scared due to the wavy red line issue, loud iris, loud fan, poor convergence, exploding bulbs, etc....
Long story short, I manned up and got the 8500 and it has been perfect since installation. I have about 1000 hours on it (mainly just a weekend user) and the picture looks as perfect as it did on day 1.
This forum isn't all bad. In fact, it's a very valuable resource. But, take everything with a grain of salt.
