I know this has been asked a lot of times on Clubsnap already and have read a few of the previous threads but they do not suit my needs. I need a tripod (with a head), in the range of $500. I want to get a fluid head as I shoot videos mainly. As for the legs, I prefer something that is multi function e.g. Detachable monopod. I'm looking for legs that extend to about 155cm. What are your suggestions? I've been considering the Benro SystemGo, and the Sirui N series, together with a 502hd head
