I have this one. It is large...8 quarts, but I like the ability to make a lot and freeze: Crockpot. I have a few older ones, one being a Hamilton Beach 6 quart unit that I've had for over 20 years and works like the day I bought it. There is a dent in the side of the body when I accidentally dropped it on the floor.
There is quality in simplicity and I think new or old, these simple designs are much more dependable and sturdier.
