Adorama has the Gitzo GT3532LSV Series 3 6x Systematic 3 Section Video Long Carbon Fiber for $449.88. It is currently $500 off for Black Friday only — until quantities last. This tripod is capable of holding a maximum load of 25kg, able to crouch down to a minimum height of 10.3 cm, extend to a height of 149.5 cm and close down to a portable length of 68.3 cm.
Gitzo tripods are very well built but extremely expensive — only in a sale like this does their price become bearable!
