My tripod and head will last me through many many cameras.

They didn't cost more than my camera, but quite a bit more than the price of the Manfrotto, after a discount.
Yeah, but if I get another free tripod bundled with each new camera...
No, I know where you're coming from. There is immense satisfaction in owning and using a truly top-quality piece of equipment. Very likely there are situations where your tripod would serve you better than mine, but for what I do, my tripod suffices.
"...many, many cameras." ?? In that case, perhaps you should spend less on tripods and more on cameras that will last longer. [sorry -- couldn't resist.
