Automatic oven shutoff. On many ranges, this turns off the oven after 12 hours. It's quite useful. A new range design that shows promise is the double-oven arrangement debuting with Maytag's Gemini smoothtop model. Prices have come down on some smoothtop models in recent years, but they still typically cost several hundred dollars more than coil models.
Repairs cost more, too.
Yet a smoothtop has a few advantages over a coil cooktop, the chief one being easier cleanup. You can also use a smoothtop as a temporary counter when the surface is cool. Smoothtops are still new enough to lend dazzle to your kitchen. Whether that's worth the extra cost is your call. Many smoothtops are now as fast as coil ranges at cooktop cooking.
