I would concur. I have a 100" Elite CineGrey 5D screen with a sable frame, and while the screen material is decent, the frame is crap. It wasn't fun to assemble (one of the center joints had screw holes that were too big for screws and needed to be replaced) and isn't completely rectangular. There is a very slight vertical bow inward on the bottom edge of the screen that is noticeable when I project a computer desktop. Mounting the screen material was also a bit of a chore.
If you can justify $3k for a screen, maybe it's worthwhile? For me, that's a tough sell even with the issues I have with the Elite frame. My personal opinion is that most of the light rejecting screens are overpriced, which is why I'd still buy the CineGrey 5D again, but DaLite or Carada would do nicely to fill in the gap in the sub $1200 price point.
