Randy:
I'm looking for 58" X 104". That's larger than a 4' X 8' sheet. I'd really rather not put a seam of any kind in the screen, so I'd avoid the 4' X 8' panels.
I think you've got it right with the Dazian! It would take $100 or so for me to do it in the Dazian. That's fine. To do almost exactly the same in Da-Lite would cost me $755. That's not so fine. (Da-Lite only sells mounted screens. That price is for the Da-Lite fabric mounted on a rectangular aluminum frame that would be nearly identical to the one I'd build in wood for the Dazian.)
My only thought about Tyvek was "What if my co-worker was right? If it did turn out to be close to as good as the Dazian, then it's worth doing it for $10 instead of $100." But I can't do the experiment for $10 because the minimum I can purchase is $150. If I'm gonna spend the $150, I'll buy the Dazian instead.
I'll post pictures when I'm done
