blue star rocks, and gives you the highest btu burner that is legal in a home range, plus infared burner in the oven, and at the same price or less than viking. My friends viking cant do a true stovetop sear on a steak or get a wok hot enough for us. Blue star can. When I had an issue they paid an independent tech to come out and set up my burners, then reset my warranty period. couldn't be happier.
