I too use a Record Titanium triple FD and the last year of the long arm Record RD.
I just purchased a SR 11 set up for my new [for me] S-Works Tarmac. I like the newer shifters but not the way they look. I still like the looks of the older ones. I did install the 'red' springs in the older levers and never did use the levers with the original springs [on the Tandem].
As for older Campy stuff, there is a lot of the stuff floating around on the net. I have never had an issue with eBay but maybe because I have been lucky. If your not in a hurry it will show up some day for the price you are looking for.
