Amazon offers the Tayama 5.2-Quart Stainless Steel Thermal Cooker for $41.41 with free shipping. (Home Depot charges the same, but you'll have to pick it up or pad your order to $45 to get free shipping.) That's the lowest price we could find by $6, although we saw it for $3 less in October. It continues to cook food without a fuel source using the accumulated heat inside and keeps food hot or cold for up to eight hours. It features double-wall insulation, a removable inner pot, and 3-ply encapsulated sandwich bottom.
