Whenever I go camping I always take a small moka pot with me. If you use good quality coffee then it never fails to deliver a very decent cup. It's not going to be equal to a coffee shop espresso, but it gets you 80% there. And you may be able to pick one up for 20 bucks. The only part that needs replacing every now and then is the rubber ring that seals the pot when you screw it together. Other than that they're virtually indestructible. At home I have the large De'Longhi, but if that can't be used there is always a moka pot on standby.
