Without a max price, we can no help. Tripod quality, unlike most other things, almost always determines quality (especially in the build and weight department). A quality, lightweight tripod will set you back a few hundred. Unfortunately, throwing in those two requirements makes a tripod expensive, otherwise you have to choose one or the other (quality -vs- lightweight).
- Cheap: Heavy but stable or light but unstable.
- Expensive: Heavy or Light and able to hold heavy DSLR+Lens combos, stable, etc.
- Cheap: Horrible quality plastic making it unstable with crappy leg controls (that slip or are difficult to use).
- Expensive: Carbon Fiber (or other exotic material) that remains stable.
My favorite lightweight + quality tripod is a Gitzo (I have two of them, one larger, one smaller).
