I don't, can't afford it. I got a quote from: http://screenresearch.com/ and it costs upwards of $5,000 for a 100" diagonal 4:3 conventional screen. i can't afford it yet. right now i'm stick with ultra low budget (da-lite manual pull down 100" same config for $270 =). but i've demo'd the alternate perf screens (along with clearpix) and they compromise on picture quality compared to the clearpix =). if i do get one, that's the screen clothe i'm getting =).
