Screen material

[ClickHere2Surf]

For over a year I have been using a home made 72" screen made from a bed sheet I got just for that. I used to hang and unhang it every time and from all that wear the frame fell apart and is only held togheter by the bed sheet which now has a 1-2 foot tear in it.

I now want to re-design my room with a larger screen (90+ inches) permanently hung on the back wall. I have read that real screen material (I.E.: not bedsheets) makes the image quality a lot better.

I have a 1300lumen projector which I run in 1050 lumens eco mode, and it has 450:1 contrast ratio and the contrast doesn't bother me much at all even in dark scenes, but if a screen material can make the contrast even better I definately want to get that material.

How muchcan I expect a 90" 4:3 peice of screen material to cost (I will make the frame myself)?

Also, which would you recommend for my 1050 lumens 450:1 projection?

Thanks
