The most important thing to look for is the wattage of your oven. The higher the wattage, the more energy the oven will require to heat up. If your microwave is over 600 watts, you should look for one of the convection-type ovens. You will want to ensure that the microwave has a turntable in the unit to help ensure the food cooks evenly. You should get a model with a good warranty (at least 2-years) and a sensor that will shut the microwave off when the food is done. There should also be a timer. If you purchase a home that was built 8+ years ago, you may need to upgrade the microwave and other appliances to bring everything up to today’s technology, and to suit today’s styles. Whatever your reason for needing to purchase a microwave, consider the following tips before you buy.
