Front derailleur recommendation

[nfmisso]

Hi All;

I am looking for recommendations for a low end front derailleur for commuter bike. It will have a 53/39 chain ring, and a 7 speed 12-32T cassette.

Thank you

Front derailleurs aren't particularly expensive anyway, but I'd have thought either a Shimano Sora or Tiagra double should be fine.
