Anybody with Stewart FireHawk Screen?

Anyone having the motorized retractable ones and have owned them for more than a year? What are your comments on the picture quality and on the screen developing ripples?

They have claimed the FireHawk will be able to work in ambient light situations which is interesting. And also, retractable pull-down screens are often claimed to have the disadvantage of developing ripples and uneveness. Will this be the same with the much touted Stewart screens?

Your replies may cause me to burst my budget for going for this expensive screen. Thanks.

Ryder,

The Stewart screens are "tab-tensioned".

There's a cable on each side of the screen that is pulled
into a big arc - convex side toward the screen. The force
to do this is provided by little tabs that connect the screen
to the cable. Thus the screen is always under horizontal
tension to prevent ripples.

The weight of the baton at the bottom provides the vertical
tension to prevent ripples.
