Front derailleur (Question for sellers)

I have an old Santana tandem with TA/Mafac/Campy equipment. It was an
early triple crank... the issue is that the front derailleurs in the
early to mid '70s were designed for double chain rings. My (well
worn) Campy Record unit won't quite reach no matter how I adjust it
and the BB.

I'm looking for a replacement that is of reasonable quality and has a
1" clamp. (I know that quite a few mail-order shops are represented
here.)

Given that I *must* shim, what modern derailleur would *you* use on a
vintage bike? I'm more into the antique equipment and haven't really
kept up to date, I fear. In your opinion, what's the best "bang for
the buck" in, say, a $60 unit?

Just about any modern triple will work, and only Record, Chorus, and
Dura-Ace cost over $60.
