I have recently built a Screen Research CH screen for a client and it is our first AT screen besides the Stewart Microperfs.
I have to say the building the SR seemed like a convaluted way to build a screen. We wound up cracking and breaking several of the snap in pieces since they are made out of hard plastic.
I have a hard time justifying doing any more of these screens after it took me and another really experienced person 5 hours to finally get this screen on the wall. And after talking to tech support, they told me that I have to figure out a way to keep the screen on the wall! I drilled holes in all 4 corners in the metal brackets to hold the mount to the wall.
The only other option, to my knowledge, is the SMX. Any one have any experience with both or either to voice thier opinions?
