I'll second the perspective on the amazing quality of everything from Really Right Stuff. I actually bought their travel tripod
http://www.reallyrightstuff.com/s.nl/it.A/id.7822/.f about 15 months ago and could not be happier with it. It's small and lightweight (carbon fiber) enough to strap onto a backpack for the whole day. But I didn't compromise anything with stability at all, even with the center column extended in nearly all conditions. However, the price point of RRS gear is out of the realm of what most are willing (understandably) to spend on a tripod. For me this was the 4th tripod I've owned and I think I've found the one that meets met needs the best overall.
The one overall piece of advice I can give is before spending money you need to put your hands on as many different models from different manufacturers as you can. If you buy solely based on online reviews and ads, you will over time end up like I did with 3 tripods in the closet and a 4th one that I use in the quest for the right one for my needs. Visit local camera shops and look at what they have, pick them up and see how they feel and how stable they are before making your selection. In my case I had the opportunity to visit the vendor floor at Photoshop World in Orlando last year so I could see everything and talk to the manufacturers before making my decision.
A growing number of people are really liking the various models from MeFoto for good pricing and quality balance.
