I can thoroughly recommend the Velbon Luxi range but for travel change the head.
Velbon - LUXi L
Its small light and actually really good. Its not perfect, but it is very very good and more versatile than anything else I have come across
NB - FOR TRAVEL where weight and size is a premium. If you have the space and can carry the weight heft something much bigger.
Alternatively there are a variety of bean bags with a screw thread attached which are remarkably useful.
THE pod - Tripod Alternative
I have one, and when i went travelling I took out the recycling plastic beans and added coffee beans, sand - whatever you find wherever you find it when you get there.
This is really useful when you prop it against something to create added stability out of anything eg walls rocks, window sills bike petrol Tanks - instrument clusters.
