The California ADA calls for no higher than 48" to the center of the operating handle. I always put mine at 42" because if you walk into a room and stick your finger out like you're going to turn on the light that's right about where it is.
I can build anything you want if you draw a picture of it on the back of a big enough check.
There's no substitute for hard work....but that doesn't mean I'm going to give up trying to find one.
