Best for everyday cooking and economy. More money buys more features and style, including slide-in configurations, stainless finishes, dual fuel, and pro-style models wider than 30 inches.

But pro-style ranges can cost thousands and are often out-cooked by mainstream models; some brands have been repair-prone. All lack the flexibility of a cooktop/wall-oven combo.

Best for the flexibility of separate cooking areas, especially if you're remodeling. Some cooktop-and-wall-oven combos can cost less than some stand-alone ranges, especially gas ranges.

But installation costs more than for a stand-alone range. You'll also find a growing number of stylish and competent ranges for less than you'd pay for many cooktop/wall-oven combos.

Best for space savings and convenience. Many over-the-range models often offer convection. And most now include a sensor that prevents under- or overcooking by adjusting cooking time according to the steam produced as the food heats.

But none of the over-the-range microwave ovens we tested could match most range hoods' smoke-capturing ability.

Best for venting smoke, fumes, and cooking heat. Range hoods are becoming as fashionable as they are practical; stainless models cost well under $1,000.

But you'll have to find space for a countertop oven if microwaving is a part of your cooking. While good under-cabinet and wall-chimney models often cost $800 or less, island models can easily cost $2,000 or more.
