Yep, good tripod head's can be spendy however once bought, they should fit onto any quality tripod if and when upgraded.
If I had Graeme G's tripod, going off the link posted, with a replacement Ball Head and camera/lens combo and I discovered stability issues, I would adapt the tripod. I would not extend the central tripod column, only because I had a tripod with a central tripod column. I discovered that when extended doing this introduced movement with the camera further away from the stable platform of the tripod legs. I would probably only extend the legs about half their full length and have them as wide as possible for a stable platform.
The tripod looks like a very capable travel tripod for a small camera Lens combo, and going off the video that accompanied it, suggests that it isn't really intended for a big zoom lens. It will do the job but not as well as a more sturdy tripod and appropriate tripod head.
My current tripod is a Benro with a Manfrotto fluid head. Thr Benro came with a fluid head but it wasn't as robust as my Manfrotto so I mixed and matched.
