Does a "Hot Pot" count?
These usually have a plastic body, low price, heated non-stick plate is most of the "floor" of the otherwise plastic tank. Sort of a poor relation to the stainless steel electric kettle. The term Hot Pot is used generically- believe that the Rival brand actually calls theirs Hot Pot. Rival, West Bend, Hamilton Beach, Proctor Silex, & many other brands all have one or more versions- but you may have to get it online. Several house-brand versions available too. I just checked, Amazon has the Rival for ~$11.
They're still pretty popular with college students, especially dorm residents.
Walgreens carries a line of small kitchen appliances/gadgets called Kitchen Gourmet, normally priced at ~$10 each. I have 2- one is a small, 1.5 qt Crock-Pot-type slow cooker(this thing is *It* for making a batch of Ro-Tel dip!
). The other is the hot pot, capacity ~1 qt., will boil water *fast*. It's excellent for making tea, hot chocolate, instant soup/oatmeal/grits/Ramen noodles/pour-brew-it-yourself coffee, anything requiring up to a quart(liter?) of boiled water. You can turn it down & just keep the water hot for a long time too. Got the little mini-Crock Pot & Hot Pot on some kind of arcane WG compound discount that finaly worked out to ~$6.50 each.
Here's a link to someones review on the Walgreen version, includes a pic. FWIW, it looks almost exactly like the Rival.
