If your primary requirements are price and weight, I would second Chris's suggestion to look at Feisol.
They are good tripods, they may be just as well built (or better) as anything under a Gitzo in price, they may have the best factory support in the business (even better than Gitzo), and they sport lower weight than many or most or all in their leg diameter classes.
I'm only hedging on build quality because I do not find that an easy thing to pin down. I find it better to just avoid the subject as best possible . They are not built as well as Gitzos but the trade-off is the lighter weight you are looking for, at a very attractive price.
