Manfrotto 055B Pro with a sturdy 3-way head is my weapon of choice. It will even support my 8x10 conley (which is a pretty lightweight 8x10), though it's more suited to my 4x5 and smaller cameras.
I think it's called the 3221B Pro in other countries (like the USA).
What I like about it? Quick setup, high flexibility (inverted or sideways column), not too heavy, sturdy, tall enough to get things about up to my eye level (I'm 6'2).
I've put the column sideways to shoot straight down with my 4x5 and while it's a bit prone to vibration, with some care it works very well. You can hang the camera upside down between the legs as well, which is great for low-angle shots and macro of ground-level things.
They have a lightweight composite version of the same tripod, don't remember the model with certainty - "MF3" maybe.
