I just received a leg section for my Gitzo 3540LS from www.gitzospares.com - actually Studio 1 Ltd - a UK based company that services Manfrotto and Gitzo products. I ordered the part on Monday and received it on Wednesday morning via FedEx. Normal shipping was free, and I paid $16 for expedited shipping. The price was slightly less than quoted by Gitzo/Manfrotto in the US.
The US repair service is C.R.I.S. in Chandler Arizona. Gitzo parts still come from Manfrotto in New Jersey. Both were out of stock on the part I needed.
For what it's worth, Gitzo's factory in Italy is on holiday during August. Normal shipment to the US once they open is 4 weeks.
I highly recommend www.gitzospares.com and Studio 1 Ltd.
