Induction is magnetic electric heat. It is 90% efficient, and thus is way faster than even professional gas. It is also virtually child safe and requires less venting. About 10 years ago, induction was offered only as a cooktop for about $3500, now it is now cheaper even as a whole stove.
The best Induction Ranges:
Electrolux - approximately $3300: Great technical, feaure-laden range with two ovens. You can bake and broil in any mode effortlessly.
Samsung - approx $1829: Decent all induction range with a warming drawer...Not as easy to operate as the Electrolux, but a good value.
Frigidaire - approx $1350: Hybrid induction with 2 induction burners and electric burners as well. Frigidaire is a great value with convection and warming drawer as well for a few hundred dollars more than a standard electric range.
