The choice of tripod and head is huge, but it all boils down to what you want it for and how much you are prepared to pay. The majority of tripods that come with an head already attached are usually a compromise and cater for the general clicker, some are better than others. If your main interest is macro and landscape where you don't intend to walk very far, then go for the sturdiest tripod (within reason) that you can afford. If you want a more versatile tripod that is light enough to carry on long treks but still solid enough to lock down tight, then have a look at some of the Chinese tripods and ballheads such as the Benro, they've improved tremendously and the latest versions are on a par with Giotto, Manfrotto, Gitzo etc, and in some cases exceed their quality. I purchased a Benro C-298M8, see here.

The versatility and quality of this combination was just what I was looking for without breaking the bank, 1/3 of the price of Gitzo and does the same job. A friend of mine bought the Gitzo version just before I bought the Benro, to say he was dischuffed would be an understatement. I use mine regularly for macro and landscape with the ballhead, I also use it for bird photography with a Bilora fluid head and a Nikon 500 f4, it's a great tripod.
