This is expensive, but they work well, and run several years on a single 9V battery. The trick is using a FLASHING LED rather than a steady glow one. I have several of these boxes, and the only bug I've found is that the LED flashes merily away when the box is disconnected from the phone line, but that's a minor problem. I'm afraid that AT&T might be the right choice, check out your friendly Death Star Store. Ole -------
