I purchased the Sirui N-2204 (carbon fiber, 4 section legs) with their K-20X ballhead about 6-10 months ago and I love it. Yes, it's an Asian manufacturer I hadn't previously heard of, but the reviews were great and they offer a 6 year warranty-- so at least they are confident in their product.
Regardless, I would recommend the tripod to anyone. Even with my 5D and 70-200 2.8 IS on top, it is rock solid. Plus it's light, easy to travel with and simple to use. I haven't given it a lot of abuse yet (besides a bit of snow and rain), but I haven't come across any issues yet.
Anyways, you can look up reviews elsewhere-- but long story short, I'd recommend Sirui without a second thought.
