Shopping recently for my Bodum Santos coffee maker, I came across the Royal Pays-Bas. Now this is impressive. Working on the same principle as other vacuum coffee makers, the Royal P&B goes the extra mile to include some additional mechanics to optimize the operational and aesthetic experience.
Interestingly, they are going on ebay for half of their list price. Might be worth your while if you have some spare cake and a penchant for strong brew.
