A fixed frame screen will always outperform a retractable screen and will be considerably cheaper. If you could possibly do this, I would highly recommend it. You don't have to spend $4K for a fixed frame model. I paid $1700 for my 110" 16:9 Luxus Deluxe Firehawk from a local dealer. If you have any ambient light or have light colored walls or ceiling the Firehawk is outstanding. I evaluated several screen samples before buying the Firehawk. I think it is the best of the "gray" screens, though Grayhawk is also pretty good. However, in an ideal environment with no ambient light and all dark surfaces, I would chose a gain of 1 white screen over it, due to better color and brightness uniformity. Stewart is really good about sending out samples, though it may take a while to get them. You should get samples from each manufacturer before you make a decision.
