We love our Cuisinart PerfecTemp - it is fast, quiet, easy to fill, is metal, and has 6 different temps - 75, 80, 85, 90, 95, 100degC, so you can have the right temp for the type of tea/coffee. And a keep warm function, which is great for entertaining. Also is cordless with a round base, so you can put it on at any angle.
