Hi Rick
I built my own screen. I bought some screen material on ebay, then used some 1/4 strapping and L brackets, wrapped the strapping in black felt. Took about 4 hours with help of my wife and for less then $200 we have an awsome 136" screen.
I am using the AE900, and the picture is great. I still have at least another 1500 hours left on the bulb so I won't be in the market for a new projector for another 3 to 4 years.
Now this screen option only works if you have a dedicated room like us. But it did save us many hundreds of dollars and I don't feel as I have given up any picture quality doing it this way.
At the sizes we you are talking about, I don't think the black bars on the top or bottom will bother you for 2.35:1 movies. I don't even notice them.
Now if you need to get the screen out of the way, then the DIY option won't work.
See this thread for pics.
