For anyone who has only just begun to realize they may have a coffee making issue and want more than to tolerate instant coffee or inconsistent hotel setups, look at the PRESSE by Bobble. I got one to serve purely as a travel press, and it solves that issue. Not to mention that it serves as a travel coffee cup as well.
I used it for the last two weeks in England and the Netherlands, making two to four cups of coffee daily. It performed flawlessly.
Instead of a traditional French press plunger, the design uses a solid internal sleeve with a single-piece stainless steel micro-filter screen that nests into the outer cup. This filters perfectly and keeps the grounds trapped securely at the bottom. The sleeve inserted and pressed down will prevent over steeping. For tea drinkers this will work as well with loose tea blends.
The 13 fl oz capacity is perfect. It has a small foot print with no protruding handles or delicate parts, making it easy to maintain and clean. For packing, the size makes it easy to slip into luggage, and it fits perfectly into the water bottle pockets on packs. If you want real coffee while traveling light, this is the press to get.
I bought it back in August when the price dropped from $18 to $10:
