I'm just disappointed by Manfrotto at all levels. Maybe Italian alloys for tripods are the same as Italian cars ... Anyway, I've got a tripod, quite expensive, and the leg fixations fully cracked because of cold, magnesium I think.
There is a brand who never disappointed me over the years : Vanguard
Have a look at the Vanguard Alta Pro 253CT, a carbon one, very solid and practical. Can carry 7kg and weight only 1,6kg. Points are in the foot, just need to screw the rubber balls.
For the head, have a look at the Vanguard SBH-300, sliding tray included. Perfect tool for "3 shots pano", very solid, very well made.
All of this will cost you under 400$, the head alone is around 70$.
