Best Budget 100" Fixed Screen that is $500 or less and 1.0 gain?

I am very happy with my Jamestown 110" cinewhite 1.2 gain screen gotten for half of your $500 delivered. Unless James has solved his backlog problems be prepared for a 3 month wait (it was still worth it). Solid 3 1/2" frame covered with real black felt and great screen material. Very much like a custom home made frame. The elite ez-frame screens are OK if you want a good comercial grade frame with a sprayed on felt covering, smaller frame, and not as good screen material for a little more money but get in a few days.
