The Slik Pro 700dx is an excellent value-solid, well made, not expensive. Giottos is another very good brand. I have a Giottos MT9371, it is a step up in size, which lets me comfortably tilt the camera upward without getting a stiff neck. I also have a Feisol carbon fibre CT 3442, which is great for carrying places.
One advantage of the heavier tripod is that it is less top-heavy. This is a real advantage in a situation where the tripod might get bumped or trip someone who isn't watching their step.
