Thanks to all for your input and advice! It looks as though I will going down the eBay rabbit hole, just scored a one-armed racing triple. Now it's on to derailleurs and a bottom bracket. I'm sure I'll have many more questions concerning what is compatible with what in the future. As far as low-end campy group, I had been looking at the Athena triple groupset, but no one seemed to be selling them. Thanks again, Jim White.
