Hi Daverwelfare,
Yes I ended up getting them: Benro tripod with vanguard head. And I am happy with my choice. I haven't tried the vanguard tripod so I can't comment on that. My benro, I used it with only 16-45 lens on kr body and didn't notice any play. It feels solid, I can push it down real hard and don't see it moving as I write this post. I feel it should be fine holding more heavier camera and lens. From what I have seen on the internet, benro's center column lock might be solider than that of vanguard. It is a cylindrical bracket that squeezes the center column from all sides, whereas vanguards center lock looks like a single bolt that simply pushes the column to the other side of the outer bracket (correct me here if I am wrong). Comparing the two, I think vanguard has more safety features like vibration control and a button at the end of the center column that prevents it from falling when pointed downward. Benro has none of these; so you have to be little more careful.
Here is a review for similar benro pod (bigger version); it has the same feature. Speaking of benro, the legs feels little weak, I tend to pull them outward from where they are to create more tension. But I had no problem taking 30 min long exposure by adding weight.
All in all, I like my tripod; I am satisfied.
