I can give you a little insight from past experience. I have used projectors, mainly for presentation pourposes, and I can tell you that there is a huge difference between "homemade" and other purchased screens. Even using a WhiteBoard, dry erase board, is not even close to the quality you can obtain from a screen designed for projectors. some have a slightly textured surface to keep the light from reflecting all over the place and direct it back to the viewing area. If you truly want the best image, I would look at Ebay and see if you can come up with a screen that will fit your budget. I don't think you will be dissapointed.
