I've got the Velbon Luxi F - maximum height of 160cm but folds down to 39cm, weighs 1.3kg, and quite happily supported my 350D with 70-200mm F2.8L IS lens.

Available for 62 quid from Jessops, of all places - at the time I bought it that was the best price, although that was a year ago so that's probably changed.

There are some good reviews for it online too, although it's obviously worth remembering that's it's designed specifically to be compact and light, so it's not going to match up to some big behemoth.
