I have two of the Crock Pot brand with the latching lid. Problem is they are 6 or 7 quart which is way large for a couple of people. Its a shame they don't make a small one, 3 to 4 quart with a locking lid.
I very much like the idea of the silicone grill mat, cushion, insulation, and it plugs the drain so food doesn't clog it.
This should be in "Home Making on the Road"
