Good to know we can use cast iron as I was told we couldn't all these years. My sister has a gas stove and that's one reason why she picked it from the glass top style. I'm still using the stove that came with the house which is glass top and was seriously considering getting a gas type though it would cost more to add the gas line, etc but now I may stick with the glass top. I realize you have to be careful but then you have to be careful with any type of pan you use on the glass top type. Mine already had scratches on it so just waiting for it to die so I have an excuse to buy a new stove.
