Hey guys just got a projector now Where can I go to get a fixed 4:3 screen approx 70-80 inches that's not 1000.00.
Does anyone sell a frame kit?

How big? You can get a 4x8' sheet (or possibly 5x8') of Wilsonart laminate, color Designer White D354-60. It makes a near-perfect 1.3x gain DIY screen, it's cheap, and it's pretty much indestructible. The gain is great for CRTs, but you might notice a tiny bit of hotspotting with bright digital projectors. I use it with a 1300 lumen JVC RS-45 and it looks great.

Yeah I made my first screen out of blackout cloth too. Didn't paint it though, I just went with the 1.0 gain of the cloth. So @garou81 (are you a OPM fan?? ) if you want 1.0 gain, a blackout cloth screen is cheap and simple. If you want 1.3 gain, I'd go with the Wilsonart.

yeah I'm studying up on the wilsonart material. I can make my own frame easy enough I just dread cutting stapling the material. I cant cut or draw a straight line to save my life. I know I need a high gain screen so the 1.3 wilsonart will be perfect but what about alr screen material?

alr? Ambient light rejecting? The only ones I see are just low-gain gray screens, with gain of 0.85 or so, unless you get into the $500++ range. And I think most of those are intended for use with extreme short-throw projectors, the ones that sit maybe a foot in front of the bottom of the screen.

If you want ludicrous gain look for a 13-15 gain silver screen. Usually fiberglass. Expensive to ship though. I liked mine. Especially for gaming.
My regular screen was a Stewart Studiotek 1.3 gain 4:3, 110"
I used that for a dozen years or so. Nice screen and you could see the difference as compared to the white wall.
I also played with Wilsonart back in the day. I ordered some and was quoted $115 then the store informed me it was
going to be $430 so I said No thanks.
I paid $600 ish for the Stewart from a forum member back in 2008 or so.

Yeah that's not a screen, that's a freakin' mirror! You'd have to curve it. Compound curve as Kal says -- not just a left-to-right curve, but a L-R and top-bottom curve making it like a dish. Then you'd have to sit in exactly the right spot, at the focal point of the screen. Sit a few feet to the side and your brightness will drop off drastically.
