Manfrotto for that price is good....
Well to start with, if you need a tripod, buy a tripod. Dont expect the legs to help much. Yes they do support the camera well, even with a heavy lens (total weight was around 4 pounds). But as you take the tripod higher the sway increases. So you wouldnt want to regret with your costly gear. Use this as a monopod and theres nothing in the world to compare with. Of course carbon fiber would have made it lighter, but then its great to have it beside you even for your treks. Strong and sturdy and even with the 500mm Nikon primes, there so much stability when you hold the cam. I have still to use it for my macro, but then holding a 1.8 pounds lens with a equally heavy body with bare hands and that too still, I guess this will be a much better choice...
4 marks for construction quality, 5 would have needed carbon fiber
4 for ease of use (self standing), 5 needed a free head with this at least as a starter kit
