" The yard is filled with hungry guests, the grill&amp;#039;s loaded with food, and then\u2014before Dad has finished cooking\u2014the grill runs out of gas. To make sure this never happens again, get him a good gas gauge for Father&amp;#039;s Day. We looked at four and found the Electronic Gas Level Indicator (gaswatch.com, $30) both accurate and easy to use. It installs between the tank and grill connection and connects to a display that&amp;#039;s placed on the side table (others had displays on the gauge itself, which were hard to read when installed on the tanks). As the gas level dips, the readout goes from green to yellow to red. When it turns red, a buzzer warns that levels are low. Keep in mind that readings are estimates; if you plan a whole afternoon of cooking, your best bet is still to have a spare tank on hand. "^^<http://www.w3.org/2001/XMLSchema#string>
