Most manufacturers offer a full line of cooktops in a variety of configurations.
Consider your cooking style and look for the right combination of features to get what you really want. Some offer choices of grills or griddles or even special wok burners. Don't assume gas is better. We all know how easy it is to cook with gas, but today's electric cooktops can sometimes outperform gas. They heat up fast, typically do a better job of simmering, and some models have nearly infinite temperature adjustment.
