Amazon has the Proctor Silex Electric Kettle (One Liter) for $10.99 with FREE Super Saver shipping and $25 purchase.
I do have an electric kettle and I love it in the winter. I drink a lot of hot tea and it takes less energy to heat the water and a more consistent heating than the microwave. It is also great because the kids are able to make their own hot chocolate and instant oatmeal because I feel safer having them use it than the stove.
