When I travel I use a Gitzo carbon-fiber tripod with their magnesium ball head. The tripod has three leg sections. I've had it for several years so I don't know the equivalent model # now. I'm sure it is out of that price range but there are other brands with similar characteristics. The point is that I use it with a Hasselblad and up to a250mm lens with no problem. The tripod and head weigh about 4 maybe 5 pounds together. Folds to under 24 inches and supports 15 - 20 pounds.
