Diva was the company to market an induction cooktop in the late 1990s (GE and JennAir tried unsuccessfully in the 80s). Induction is the dominant cooking technology. It is faster to boil and simmers, emits much less heat for easier venting and is child safe (not child proof).
Back then the cooktop sold for $5500
Today it is much different as you can be hybrid induction with half electric and half induction burners as well as all induction
All induction: 2400
This is interesting, you can buy this Frigidaire hybrid range with convection and a warming drawer for the same price as the cooktop...hard to believe.
All induction $2499
