Think about something for me a minute. When you buy a projector that is worth say at least $7,000 why would you want to spend $200 on a screen? After all, what is it that you are looking at when you are attempting to view the image? The screen of course, so as is much of life, you get what you pay for in a screen. Indeed the manual pull down you now have is not designed for a Home Theater setting. It was designed for a classroom. If you have kids (and they are school age) I am sure you have seen Da-Lite screens in their school.
If you are looking for an inexpensive, but upgraded alternative to your current screen. I would recommend looking at either a fixed wall screen or a non-tensioned electric screen. I am confident that if you spend a little bit of extra dough on the screen you will be happy with the results.
By the way, I am confident that the screen manufacturers are not making much in profit. I used to work closely with one of them in a previous life and can tell you from experience that some of their screens are just an accommodation sale (at least on the non-consumer side, not sure about this side).
