Thanks for the assistance. $1200 is a little more than I was looking to spend on a tripod and head setup. I'm a newbie when it comes to this gear. By clamping system, are you referring to anything more than the head?

The 190CXPRO4 has a lot of good reviews. The 468MG has several options with a "quick release" on it. What do I need too consider when deciding on a model?
