Hi, Koko! I can't quite see the advantage of such a large one (16 to 20 quarts?) as wpozzo is looking for, but I have to admit that now that I have a crockpot, I'm very happy with it. I don't have to watch it and stir the food to keep from sticking to the bottom as it would on top of the stove, and it supplies its own oven-type of surrounding heat, without heating up the kitchen as the oven would. And it's great for making a big batch of congee!
