Custom DA-LITE Curved Rear Projection Screen - $1500~
This is a custom 35x88 Da-Lite (DA-100 HC) curved rear projection screen (High Contrast version) that I've used for racing simulators. As you can see in the pictures I only used the bottom half of it. It can be used with just about any project setup you can think of. I stopped messing with projectors some time ago, so this thing has just been sitting the corner.
I'll post the specific dimensions as one of the pictures.
The price is negotiable, shipping is going to be a pain if even possible.
Contact me if you have any questions.
