I know the girl also told me the earlier Gitzo pods, when water got into the locks (taking pictures in a stream), it would make the o-rings swell up and you couldn't collapse the legs anymore. I don't know if the problem has been fixed...
I've also got a venerable old Slik tripod that was designed for big cameras. Its an SL-67 Prototype with panoramic head. You need to use a rotating back on it since it doesn't have side to side motion (it was designed to hold a 6x7 camera, not exactly small). Its heavy gauge aluminium, weighs a ton, has steel leg braces, goes up to over 6 feet (2 meters) and has a rack and pinion column adjustment... Used it for years but it's now in semi retirement since I got my Manfrotto.
Jimbus:
One thing about the tripod heads, you have a choice on both Manfrotto and Gitzo. Depending on your shooting style, you might favor one over the other.
There are the ball heads: very flexible and smooth on one hand, not precise on the other.
There are the 3D heads: all directions can be locked independently so it isn't as smooth as the balls, but close to the best for precision.
There are also gear heads: they use precise gearing to adjust the camera position, only useful for view cameras and studio work.
The fluid heads are only for video.
Balls are great for sport photographers who use them basically to take the weight of a long 300mm lens while leaving plenty of free movement. Bird watchers also prefer them.
I chose the 3D head for mine. I figured that, when I need a tripod, it's for stability and precise camera placement. It's a good choice for me and I don't regret it for a second!
Quick-release plates are also a must have. Make sure you buy extra plates for the cameras you plan on using. I know it's expensive but it's so much fun when you don't need to unscrew the plates when you change cameras!
