Are you sure about it being light? Usually heavy is best for supports. The old chestnut for tripods is that you can only have 2 from the "triangle" . . .
1. Light
2. Cheap
3. Sturdy
Red Snapper do a good range of quality supports at good prices. There's also lots of good used available at the likes of Ffordes, MPN, LCE, Park Camera etc etc.
