cats - cats everywhere!
Anyway - with tripods a lot of the choice has to be determined by use - consider these points:
1) weight - a lighter tripod is easier to carry on longer trips (especially if you have heavy other kit to carry - lenses, cameras , tent

). However lighter tripod also means its got less balance when the camera is on top (its centre of gravity is higher therefore its less stable). This can be countered by hanging your bag/kit/rocksinabag off the tripod - most have hooks for this.
2) Carbon fibre tripods are worth the money, though are usually double the cost of a tripod with the same statistics load capacity, height and other statistics. The lighter weight and balance "problem" that many see is often countered by the about point 1 - often this is easy as people that go for carbon fibre are usually carrying a lot of other kit with them
3) usage - what are you going to use your tripod for? Landscape shots, macro, fast moving cars, wildlife etc.... work this out and it can help you aim for a tripod best suited to you
4) Usage with regard to heads - tripod heads are even more defined by what usage you will be needing - a 3 way head is great for landscapes, but not so good for tracking fast moving birds in the sky -- in counter a ballhead is great for birds, but less suited to landscaping (especially panorama). Often some people will have more than one head for different uses.
5) budget - consider not only your current budget, but how long you are willling/able to save - a cheap tripod today might work for a short time, but won'y be best suited to a long life of hardy use and won't be one to trust to stand alone without falling

-- waiting for a better tripod is a good thing
