I also have three slow cookers, a large one that is family size that I seldom use any more, a smaller 4 quart that has a permanent spot on my counter, and a small 1-qt "crockette" for making oatmeal and other small meals.
I highly recommend the Hamilton Beach and if you have a family their newer 3-in-1 slow cooker can't be beat. Stay away from the newer RIVAL Crock-Pots because they run way too hot.
My favorite food from a slow cooker is baked beans, followed by chicken, soups and roasts.
Support bacteria. It's the only culture some people have.
