Get the perfect, cute, breakfast slow cooker to guarantee perfection every time.
Many local hardware stores sell great slow cookers for reasonable prices. You can often find them in second hand stores too. You need a 1.5-2 quart slow cooker for 1-2 people. Get a 2-3 quart slow cooker for 2-4 people, and bigger slow cookers will work for more folks. Big ovals are not ideal as you don't want too much surface area on the bottom for spreading. Here are a my favorite, tried and true slow cookers. Be sure to get a removable crock for easy clean-up. Ideally get one with a low setting. High is too hot. Single settings are usually too hot. My favorite has warm, low, high, and off.
