I got hold of a 50" 4:3 Rear Projection Screen for next to nothing a while back. http://www.media-vision.de/international/products/mds.php I use it once in a blue moon, and am looking to maybe sell both it and my projector, but i dont really have a clue what the screen is worth. At the time i got it, I heard roumors that the screen itself cost around £5 sq inch when new, which I cant really believe. The screen i have has a small crack at the edge so needs trimmed down by about 2-3 inchs so it would still make a cracking 45" 4:3 screen. Any ideas what i should be looking for the item ? Infact, i dont really know what the projector would be worth either, its a NEC VT45, with about 200 hours on the current bulb. I've seen them go for around £500 on ebay, is that realistic ?
