Just to add 2p (3c) from the UK. For once (and probably ONLY once) I can say that Britain is NOT a ripoff!
Had a look at the RRS tripod on the web and it looks like a fine piece of kit! But man it's expensive!!
I live in South Wales and buy the vast majority of my gear at a high street Camera shop about 30 miles away. In US money I paid about $200 more for my Gitzos (note the plural). I got a GT3530LS AND a GT2531 (both new) - if you add another $160 you can add a used Gitzo G1329 Mk2 systematic with a carbon center column which I bought 4 weeks ago. My 3530 has a lower weight rating (18 Kilo) than the RRS, but it has been tested with me - 100 Kilos so I am not worried about that!
The RRS looks great but they would have to knock off at least $300 before I would consider it.
