Projector Screen for Epson 6010

As my basement home theater nears completion, the time to order my Epson 6010 draws near. As for the screen to use, the only things I know I want with the screen is for it to be 110 inches (I measured the room, walls etc so I know this is the size I want) and it will be fixed frame. Other then that, I have not a clue what screen to go with. Light can be completely controlled in this room, since it's a dedicated basement theater room, and the distance from the screen the projector will be is about 11 feet. What kind of screen should I look for and about how much coin would I have to drop for an appropriate screen?

I don't know what to look for. I don't want to drop a boat load on a screen if it's not needed. I'm seeing screens that have the same gain (~1.0), same size, same type, and some are $400 and some are $2000. What the hell is the difference? Audio is my forte, but I need some help from you videophiles. I have no idea what screen would do for my set-up.

Okay, will do thanks.

Whats the difference between the two besides cost? Does one last longer? Does one result in a better picture?
