One of our regular charter crewmembers is a coffee snob, and always brings a French press. It's lightweight, quick, and easy and makes way better coffee than an automatic drip machine.

It does, however, need a fairly course grind to avoid grounds escaping the plunger. He always brought his own coffee, so I don't know how easy that would be to get locally. I understand you can use ordinary pre-ground, but you might gets more loose grounds in the coffee.
