Where else to get old Campy stuff

I was very lucky to be given a 90's Colnago Super frame and forks as a present about a year ago and wanted to build it up with some correct Campag stuff but did not realise just how expensive some of the old Record/Super Record stuff goes for. So far I have saved enough to buy some wheels, bar and stem plus rear mech, headset and bottom bracket. All my sourcing has so far been on Ebay, is there anywhere else I should look without paying too much. I am hoping to get it finished by the end of the year so can wait.
Thanks in advance.
