When I was looking to make a purchase for a new range I started comparing glass top vs coil vs gas.  I have had gas before and they cook too hot.  I read that glass tops are hard to keep up especially when using cast iron cookware.  So I went back to using coil cook top.  Glad that I did.  I was even surprised that my new range with it's timer even counts down to seconds.  It is a really nice feature.  Love the range.  Ge makes a really good product.
