If you can't find, get Sora R3030 for the left, same pull on the 5703/6703 FD. The R3000s are very decent shifters in their own right (though 9 speed). Another alternate is the 4703, I currently run 6703 on my tourer/audax/winter racing machine and the right side Tiagra 4700s are better than the 6700 for rear shifting, the front mechs are cheap and the right/rear STI can be used with 105 11 speed rear Ds which has a slightly bigger capacity and again cheaper than the 6703 GS.
If/when the 6703s go I'll be swapping for 4703, problem is that Shimano are likely stopping triple STis, Tiagra 10x3 is about the same money as Ultegra 11 speed if you can find them.

Thanks - that's helpful information. I only broke my left shifter, but given that triples have been so comprehensively removed from shimano's range so I can't really upgrade to something newer without replacing large parts of the drivetrain, and possibly also hubs / wheels given the spacing on my frame :/
I'll keep looking!
Long shot, but I'm looking for a pair of 6703 shifters, the front has to be a triple.
Decent condition etc.
