What you're shooting also figures in.
Generally, I'd want to be able to hit the subject's eye height or a little above when shooting people.
But it's also true that way too much is shot at the most convenient height for the photographer. Some subjects are begging to be shot at high angle or low angle.
I'm 5'9" and most often use a Manfrotto 190-series. With ballhead (and a little column) it gets to my eye height quite easily. I don't mind using the column for additional height - but I know I'd feel differently if I were shooting a super-telephoto. With its articulating column it gets as low as you want. If I need a truly high angle, the old Manfrotto beast that goes over 9' comes out, along with the stepladder.
It's often repeated that columns are less stable, and should therefore be avoided. It's true that most are a little less stable than a higher tripod, but unless you're shooting over 200 or 300mm, a good tripod with column does fine. I'm well prepared for others to call my view wrong-headed, but I do think that these commonly held truths should be dusted off occasionally, and see how it fits for you and your shooting!
So... what do you shoot? And do you or will you plan to own a lens over 200mm?
I've mostly shot Gitzo & Manfrotto, but the Feisols look like an excellent value.
