I saw and ad in a magazine months ago that was for a tool that allowed one person to cut ceilings for boots and gfrills for new installations. It was made of clear plexiglass. It allowed one to cut the holes and it caught all the saw dust and plaster scraps. One person could do this without the need for a tech to be in the attic cutting while anothe held a box to catch the scraps. I can't find the ad (naturally) when I need it.
