I am thinking about getting a screen to use at events. Probably no larger an event than a medium size wedding reception.
Just wondering what kind of screen you guys/girls might be using.
Type of surface?
Size?
Tripod or..?

What are you using it for?

Adam,
For projecting (front projection) video presentations. Ambient lighting may or may not be controllable. Probably using either a computer or a deck/camera to feed the projector.
Thanks for making me make it a little clearer

the Da Lite Insta-theater can't be beat for ease of use and quick setup/tear down.

The da-lite screens are the way to go for up to 10ft diagonal screens. I have a lycra screen that I use for larger presentations. It is 14X10 and assembles in 5 minutes, rear or front projection abd very easy to transport. The screen and stands was approximately $200.
