I just got myself a Nemo Morpho tent, which uses "airbeams" instead of poles for support. It comes with a foot pump to inflate the beams, which are extremely durable (not to mention cheap and easy to replace if they do somehow tear or fail), and the whole thing packs down very small and light. I'll be using it for the first time next week, but I got it after reading pretty much nothing but glowing reviews about Nemo's airbeam tents.
