I often put my recorder on a gorillapod with an articulating head (e.g., a ball head). That turns it into a three legged beast that's more stable and vibration-isolated when sitting on a nearby chair or stool or desk, and can also wrap around a chair back, music stand or mic stand, etc. If it might slip or get knocked off, I'll use gaffer tape or a ball bungee on one of the legs. Make sure the head is rated for the operating weight of the recorder, and the pod is rated for weight of recorder + head. This is a very compact and portable setup.
A mic stand with a boom is better than a tripod in that you'll have more flexibility with placement, and it'll be more useful if you ever buy or borrow a mic for better recordings. And decent mic stands are cheaper than decent tripods. On the other hand, they're heavier and don't pack up as neatly. Some recorders come with mic stand adapters, but they're inexpensive to buy, too.
