Citizen's 2.7-inch LCD model, with mirror, is similar to Casio's black-and-white set, but this one retails at twice the price, $199.95. For that, you get AM radio included, longer battery life (using four AAAs) for an advertised life of 10 to 12 hours and an AC adapter. A rechargeable battery pack, a car-battery adapter and backlight are optional. It weighs about nine ounces. Promised this summer is a larger color model for $299.95.
