A 6.5-quart slow cooker is quite large and suitable for feeding 6-7 people. If you have a big family or like to host dinners, this size is right for you. However, if you usually cook for a smaller crowd and only occasionally host groups, a 6.5-quart cooker won't suit your everyday needs. Most recipes require you to have the cooker pot 1/2 or 3/4 full, or you run the risk of drying out meats and burning your food. A 4-quart recipe prepared in a 6.5-quart pot will not yield satisfactory results. So make sure you shop for a size that reflects the amount of people you're going to cook for. All of the 6.5-quart models mentioned in user opinions have timers, a convenient feature that has earned them high scores for ease of use. They also all have dishwasher safe components and high scores for easy cleanup. The price range for slow cookers of this size is $50-$150, with most costing under $100.
