what screens (fixed & portable) for an old Proxima DP5100 LCD?

I wish to purchase a screen for home theater use with my old LCD projector- a Proxima DP5100 (specs for it from Proxima's web site below). I hope to find a deal on a used screen from a fellow AVSer who is upgrading.


Given the projector's brightness (or dimness?) what should I look for regarding gain, color, matte, glass beaded, or whatever the critical concerns should be.


All suggestions welcomed,

Kurt
