New front derailleur needed for 70's roadie, but which?

Hello all,

Unfortunately the clamp screw on my current suntour front derailleur has cross threaded. I can put the screw through from the other side, but that prevents the derailleur working, so it's a pointless fix, I'm essentially running a 5 speed with a spare chain ring.
In any case the suntour kit is slightly out of place in a bike that is otherwise running a mix of early Dura-ace and 600 parts. I've been looking online for early dura-ace FD's and have found a couple on ebay. Question is; is it worth getting these early Dura-ace bits, were they any good? Should I go for a different make? I should imagine Campag would be too expensive for me.

Thanks

Use a slightly longer screw with a nut on the end.

I don't have enough middle fingers to deal with this.

Dura Ace is about as good as the Old School stuff gets, in my opinion. Don't hesitate to use anything from the Dura Ace group.

Other options:

The Campy NR front derailleurs are very good, and price depends on condition. It's very rare to find one for sale that is just mechanically trashed. The older ones without lawyer lips on the (death) cage are more $$ than post-1977.

I like the Shimano 600, series 6207. Every bit as good as the Campy and SunTour, and the geometry of the Shimano and the Campy are nearly identical in terms of handling a wide range of sprockets.

Except for the Campy Valentino and early Gran Sport, I have trouble thinking of a really bad front derailleur.

Thanks for the replies, I think I'll go for the earlier Dura-ace I found, it's good enough condition. Also, the clamp size is listed as 28.6mm. Unfortunately I'm not at home so don't know the exact width of the seat tube on my bike. It's a very light, late 70's French roadie (at least by its components) with columbus tubing that shows the top middle sticker of these:

Going on that information, would the clamp fit the seat tubing?
thanks.

And both the ebay sellers are from poland, worries?
