Are you sure it's not just a tripod w/ tilt-able center column? Several manufacturers make them. (Benro, Manfroto, Benbo, Gitzo) , etc etc.
I have a Benro CF with it, it's a very "ok" tripod. I also have a Benbo Classic (it's huge). A Benbo trekker is very versatile tripod for macro, but Benbo's are weird to set up.
Cost of a Trekker is about the same as a boom arm.
But if you have a good tripod and want a boom arm, the
Velbon V4 is quite nice.
