After doing some research I decided to purchase the KitchenAid slow cooker.  I have used it a few times and am glad I got it.  Perfect size for a family of 5 or 6 (plus a couple of friends over for dinner).  There are many recipes for slow cooking and we've enjoyed several delicious meals already.  It's easy to set the timer and start cooking.  Go about your day and know that they'll be a hot meal ready when you return.  It's very easy to clean afterwards.   The ceramic pot can be heavy when loaded with food, but the pot and the entire cooker is made of quality materials.  We're very pleased with our new slow cooker.
