Manfrotto 190ProB* and a 460MG head, Shiato.
The combo is about 2 kilos. I don't find that too heavy, you may...
*The "B" just refers to the finish (black) the 190Pro is identical, but chrome
I hear iffy things about the Manfrotto carbon fibre tripods - in that they're not an awful lot lighter than their counterparts, but lose out on stability. I've heard that if you really want a decent carbon fibre, it has to be Gitzo.
Hope your wallet is big!
