I just purchased an aluminum benro travel angles for ~$220 (including a ball head). It has a weight of approximately 4lbs, folds to a length of 14.5in, and has a max rated load of 12kg. I find this tripod to be a good compromise between travelibility (yes I invented a new word) and stability. I am 6'3" and can use my camera without bending (with the center column almost all of the way up). If you are looking for a very stable tripod that you can still take on a plane or a hiking trip you should take a look at this tripod.
It is very stable, and seems to have good build quality. The first thing I did when I got it was take it apart
. The legs are the twist type with aluminum threads and rubber inserts over them. Inside the tubes there are plastic inserts. When the pole is screwed in the inserts are compressed by the outer tube against the inner tube, creating a solid friction fit. while the inserts are plastic, they are made in such a way that I foresee them lasting a very long time.
I have not taken the ball-head apart yet... I got the ball-head that allows panning. Overall the quality seems good, however the head could operate smoother. For the price the ball head is adequate.
