Manual or hand mills are great -
There are a few factors to consider when selecting a hand mill, such as, size, weight, and capacity, though probably the most important factor to consider is how well the mill will fit in your hand. Grinding on a handmill requires a sturdy grip, and you will want to maintain good leverage for the few minutes it will take to grind the beans. Consider a mill that you can comfortably grasp in your hand, or alternativly a Zassenhaus Knee Mill, which you can leverage between your knees. Manual mills are suitable for a drip, espresso and the finer side of a French Press Grind.
