Ready to replace my gas cooktop and have a 42" wide space. I want front knobs and would love to find a 4 burner with a flat (non-stick) built-in griddle or a 6 burner with removable griddle overlay. The only 42" cooktops I am finding are KitchenAid, Miele and Viking; and, alas, none of these models have the option mentioned. Does anyone have any feedback or suggestions for me on these models or ideas on other brands that may work. THANKS!!!
