The Whirlpool WMH2175XVS is a simple model to operate and offers value for its relatively low price tag, around $260 as of 2011. Although this model does not offer a convection option, it does have a larger capacity (1.7 cu. ft.) than many similar models, holding up to four plates at once. It also offers the 6th Sense Sensor Cooking feature that monitors the level of humidity in the food you're cooking and automatically adjusts the heat and time so your food comes out perfectly cooked.
