There are two types. One uses an engine oil dipstick to warm the engine oil. (about $15)
The other type is magnetic and sticks on the engine block and keeps the engine block warm. (about $40). I bought this more than a year ago but did not use it as last winter was quite mild (plus I was away for about a month during the coldest part of last winter). I may have to install it for this winter as the predictions are a cold winter for us this year.
Both can be purchased from Autozone or Advance.
