I've been trying to find a good tripod to get for my HF S100 camcorder (The camera itself is 1pound, I have some accessories on it which makes it 3 pounds but still pretty light weight) I've been looking around for a tripod around 200$ and found these:

I couldn't find any test footage but I heard the pro vista was pretty good, but had some slight jerky or such ending pans, and someone said to replace the head with a 701HDV manfrotto so I searched that and found this:

it's 30-40$ more but do you think it'll be worth it? also do you think I should get some sandbags to weigh it down, as it's kind of windy where I am and my cameras pretty light weight.
