i am looking for a good electric kettle that heats water to different temperatures, as certain teas steep best in hotter or cooler water. i found one which seems to be what i want- the zarafina one, http://www.amazon.com/Zarafina-Maker-Suite-Ceramic-Serving/dp/B000HJNJNO
but it is far out of my price range. and has a few reviews that make me nervous about it. are there any ideas or suggestions?
