This was one of the ways I was considering using. Essentially the limit switches on the screen shut the power off in each direction. Since the screen motor is a 120 volt motor, it probably makes sense to have some sort of master switch in line with the power going to the screen or else even when you go to service it you will still have power applied.
The transformers are available at most electrical supply stores or even Radio Shack for less than $10.
