Nowadays, there are only few companies that still manufacture vacuum brewers, only two of them in Europe: Bodum and Cona. E-bay and antique shops still sell the traditional Sunbeam, Silex or Cory, at prices ranging $20 to $50. A new Bodum ranges from $50 to $100; a Cona is more expensive, the lowest price being $150.
