I own several Manfrotto 190CX3 Carbon Fiber Tripods. Perfect for a set of light sticks under a 701HDV video fluid head working with smaller cameras. The 190CX3 regularly runs for $243 dollars (as seen here) weights only 3 lbs. and is rated to support a small load of around 11 lbs.

If that's not enough, the 055CXPRO3 is a heavier duty Carbon Fiber Tripod weighing in at just 3.6 lbs capable of a 17 pound load. Not just beefier, but also more features such as a center column that can be positioned horizontally.
For about the same price as my lesser 190CX3, right now there's a deal to receive an Instant Savings of -$150 off the Manfrotto 055CXPRO3 Tripod Legs bringing it down to just $249.

@Buster - I have plenty of these lightweight tripods. Of course they will be shaky if you're not using them with smaller systems. Sounds like you might be using a heavy setup.
Dont do it, but tripod SUUUUUX. I got it on the last deal and it is shaky and unstable....and VERY bad purchase. I regret it completely.
