This luxury drop-in cooktop kit includes 2 downdrafts, teppen yaki induction top, a cooktop with 4 gas burners and a smaller unit with 2 burners and a fan (untested). Stove igniters tested and seem functional, teppen yaki seems to heat up as well. Just a single drop-in Gaggenau burner unit can sell for well over $1000 though these models are discontinued. These units are in decent used shape though may have scratches and other small cosmetic imperfections.
