If you to go with a lighter load rated tripod, then stick with a better brand because they did not get a good reputation by over rating their product. So if you want to get a lower load rated set, then go back to the first page of this thread were Nero suggested a Manfrotto. John is not known for buying junk and he had experience with the Manfroto so I would think that is a good start.

If you are not planning on walking long distances with it, then you could probably get away with an aluminum alloy tripod.

If you are not hiking with this, then perhaps a good deal (and probably what I would do with your budget) would be an Induro Alloy 8M AT413 rated at 20 kg. It is pretty tall, but does not break down smaller than 30 inches. It costs £137.

The Induro Alloy 8M AT314 rated at 15kg. It cost £118.

And a little more compact Induro Alloy 8M AT214 rated at 10 kg. It costs £94

What I am planning on ordering next week is the Induro Carbon 8X CT414 rated at 25 kg. Unfortunatly, it costs £420, but it is tall and strong.
