If your goal is to make a screen yourself, then I certainly see no issue with it and I've heard some good stuff about their product. But, if you aren't inclined to fully produce a high quality screen and you want this for your home theater, then perhaps you may want to just get a cheaper fixed frame screen from companies such as VAPEX, Elite, or Focupix. Those are all similar quality screens with decent reviews, black velour trim, and solid entry level quality.
I have personally used both Focupix and Elite and think they are very comparable. For less than $200 for a 110" diagonal, they are excellent for home theater use.
