The Vanguard GH100 is more than just a pistol grip head for your tripod. It can act as a ball head, pistol grip and panoramic head. Check out this video from our Photokina trip and see what I mean.
Some additional videos we shot at Photokina have recently gone up on our YouTube channel. This one of the Vanguard Alta Pro Tripod is the first to go up. If you in the market for a tripod, give this one a serious consideration.
