Best Buy sells an Avanti microwave oven with manual controls for $62.99. This model has a capacity of .7 cubic feet, a glass turntable and 600 watts of power. Amazon offers the Westinghouse counter top microwave oven, the smallest, with 0.6 cubic feet of cooking space and six power levels for $58.60 with free shipping.
There are other models of microwave ovens with manual controls that are available; however, they are increasingly rare because LED controls are both easier to use than manual controls and easier to install at the factory.
