This is the subject of several threads here, and the input will be endless. I have that Gitzo, and because it was new and shiny, thought of switching to the RRS and selling the Gitzo for almost what I paid for it, based on offers I'd gotten. After reading about the RRS, I decided to stick with the tried and true Gitzo with an experience and a reputation going back a hundred years, and some design concerns I had with the RRS.
I like that the RRS is made here, but all the equipment I use (aside from RRS's unbeatable lever QR, nodal bar, etc.) is from Japan! And if you've ever ridden a well made Italian steel bike or worn an Italian wool suit, I wouldn't worry about a tripod made in Italy. The Gitzo service here is poor, but I shoot a lot abroad, and the rest of the world is Gitzo territory. It's really Hertz and Avis in my mind re the service...RRS tries harder, but the product is not necessarily better.
BTW, regarding service, I called up Gitzo in Texas about a year ago as I recall, and had the part I needed in three days. Maybe this was after peter_n spoke to people at the Expo!
