Need current sensing relay

Hi folks,

I'm looking for a relay I can put in series with a TV set to sense when it's on. The TV
uses between 175 and 240 Watts, depending mostly on the backlight setting -- it's an LDC
TV). So the current will be roughly 1.5 to 2 Amps AC. The contacts need to handle 1/2 A at
120 Volts AC. I know I could wire up something solid state, with a series resistor and some
circuitry driving a triac, but I'm looking for something simple and quick. Any ideas?

Thanks.
