Hi, just like to share my experience with Benro. Total setup cost me $410, it's the travel Angel C-169 with the B-1 ballhead. Played around with it for a long while in the store before I purchased it, works great with the 5D MKII + grip + 16-35mm titled in various angles. The legs are really stable and the ballhead (which is the the 2nd generation of the B series ballheads) amazes me, handles the setup really well, no creeping.
The best part of this is the compactness of the tripod when folded up - around 37cm (according to the manufacture's figures) or as long as my 15" macbook pro. weight is around 1.6kg(with the ballhead)
The heaviest setup I've worked with this is 5D II + grip + 70-200 f2.8, holds well and stable even when tilted off the center plane. FYI, i've also tested this combination with the aluminum version A-169 + B-1, again, I'm impressed. The difference in weight was why i chose the carbon fibre variation.
I've tried out the Gitzo 1541T + markins Q3T briefly at the store as well, and yes, I would say the Gitzo does feels more sturdy despite the lightweight. The markins ballhead is definitely feels much more smoother than the Benro B-1. But for my usage, the Benro met my needs and the price is almost a-third of the gitzo.
