Having worked on film sets for several years using a variety of c-stands, when it came to buying some of my own I went with this Avenger model. Really well made, rock solid. They are quite heavy, but I personally find this reassuring. This version has the detachable turtle base, which is helpful for transporting them if space is an issue. I bought 3 to begin with.
Pros - Build Quality, Breaks down into smaller components. Black finish looks really nice, and doesn't give unwanted reflections.
Cons - None that I can think of.
