We'd had a GE Convection Microwave in our last house. When we moved, our kitchen had older GE appliances, and when the frig died we replaced them all. I've used the convection when I needed a second oven, and the Speed Cook is great - baking with no preheat time! I've done deep-dish frozen pizza several times (the pizza fits perfectly on the tray), frozen egg rolls, but have to learn more. Would buy it again if I need to.
