We're pretty happy with the Convection microwave and simple professional 2 burner electric cooking top we have. When we do not need the cooktop I simply stow it in the cabinet we built-in next to the Bosch dishwasher. Clean look on the counter too. I think we have galley photos in our gallery here.
The cooktop is like a professional omelette cook top you would see in a restaurant or at Sunday brunch at the Yacht Club. $65 on Amazon. When it "cooks", you buy another, simple. We have never really needed more than two burners we've found, even when entertaining, and even then, the caterers would bring their own, or another if we were going "all out".
I split the 220 feeding the old Galley Maid. One Circuit just for the big Convection Microwave, and the "other side" for the cooktop. Easy.
Looking forward to your photos.
