I have used sundella board on my layout for many years now, and been very happy with it, but saying that it does need care when fixing down, as it has a bad habit of bowing, (you will probraby notice that its bowed when you take delivery of it) mine is screwed down onto chip board, it does need a good base to be fixed to, my points are operated from lever frames, so i dont have the problem with hiding point motors, it also has good sound deadening properties, and as mentioned before, the easiest way to cut is with an panel saw.
