I've got the Ceilinglink in my basement Home Theater room. I put 1/2 in of furring up to allow routing of cables, then I screwed the ceilinglink into the furring strips as well as the walls along the perimeter of the room.
Anyhow, A friend and I put the ceiling up, Worked on it on and off for a couple of days, it wasn't very difficult, though it was a bit of a challenge to keep everything lined up and square...
Prior to this, I had an old drop ceiling which was about 6 inches deep, and the grid was rusty and I was redoing some of the internal walls, so I pulled it down, and just reused many of the 2x4 tiles (though I painted them dark blue with flat paint so they would not reflect too much light.)
