We used this neat screen in EV with our LCD beam projector for ~2 years and moved out a few weeks ago.
No longer using the projector off campus, so we want someone ideally in EV to take this for $20 obo.
New one costed us >$100 with the wall mount brackets and we kept its original box packaging.
Pick up from 70 Olmsted Rd after 9pm weekdays. It's ~80" long, so you might need a cart or a truck for long distance.
