I use a 3540XLS ( I am tall ) and it is the best by far of the several tripods I own and is utterly rigid. Of course it depends what you want to put on your tripod but this tripod is easily robust enough to take a big DSLR and a huge lens like a 500mm. I also have a levelling base on it which is occasionally useful too.
Along with a good ballhead (I use the Kirk BH-1) I can't imagine anyone finding such a setup wanting unless they have very particular needs.
