I am not going to recommend any specific tripod but, rather I will give you some generic recommendations regarding tripods.
1. Normally, you have to pick two of these three parameters when choosing a tripod and cannot have all three: low price - stability - light weight. However, you can occasionally make do with a lower priced tripod that is still relatively light in weight and fairly sturdy if you can settle for a tripod which is shorter. Obviously, a shorter tripod, all other parameters being the same, will weigh less than a taller tripod. The height requirement of a tripod depends on your height and whether you are willing to bend a little to use it. A right angle finder will often help when using a shorter tripod. The shorter tripod will work for sedentary subjects but is not convenient to use when attempting to follow moving subjects.
2. I do not like a tripod which has braces extending from the center column to the legs. These braces, although ostensibly providing greater stability interfere with spreading the legs separately to work on uneven terrain or setting up the tripod in a very low position with the legs extended almost straight out.
3. I do not like a tripod which has a geared center column. IMO, the geared center column does not provide for minute adjustments. As a corollary to this rule - I do not like to extend the center column to any great degree because this often makes the setup less stable.
4. I like a tripod which will allow the camera to be placed at a very low position. Many tripods allow the center column to be reversed with the camera under the apex of the tripod. Other tripods like the U.K. manufactured Benbo (not the Chinese Benro) or the Taiwan manufactured Giottos can articulate and help place your camera nearer to the subject. This is a great asset when doing close-up or macro work.
5. A tripod which is too light to support your camera/lens package is almost useless. I agree that you should halve the manufacturer's maximum weight recommendations and see how that matches up with the camera/lenses you will be supporting. However, if you have a tripod which is too heavy to be carried, it will not do you any good either. No tripod which has been left at home can support a camera in the field.
6. I much prefer a tripod with a ball head for the majority of my shooting. I also like a tripod that has an Arca Swiss Compatible quick release. The Arca Q.R. will allow the use of a really Right Stuff L-Bracket. Although this bracket and Arca Compatible Q.R. systems are expensive, they are well worth the price and can often allow the use of a lighter weight tripod and head.

You can often attach an Arca Compatible Q.R. to a ball head such as the Manfrotto 488. This will allow you to use Arca Compatible plates with the manfrotto head.
7. Often tripods which are sold new with heads attached are not the very best grade. Better grade tripods are usually sold without heads so you can select the head you desire. I bought a relatively light weight SLIK tripod which is surprisingly stable but which came equipped with an inferior head. I replaced the head with the ball head I use for my larger Giottos tripod and the SLIK works pretty well. Of course, the head weighs half as much as the tripod itself and costs twice as much.
Finally, many photographers, myself included, have gone through a series of tripods and heads before they find the one which they enjoy using. I have finally settled on two tripods - one which is relatively tall and very sturdy and another which is somewhat shorter and lighter in weight. I will use the larger and sturdier tripod when I do not need to do a lot of walking and when I am using long and heavy lenses. I use the lighter weight tripod when I am hiking long distances.
