Does anyone know where I might obtain a controller (keypad) for a Litek-LM20002 LED message board? I'm sure someone out there either has one or knows where there is one. They couldn't all have vanished off the face of the earth! I moved and either totally misplaced mine, or left it behind. I hate to think that I'm going to have to throw the sign out if I can't locate one . . . please help!
