I'm not quite sure I agree with this. I think the difference between a higher-end versus a lower-end front derailleur is much more noticeable than the difference between different grades of rear derailleur. I know my Ultegra FD shifts much more crisply and easily than my 105 FD, though there is not much difference in the rear shifting (one bike has full Ultegra and the other has full 105).

I wouldn't skimp on the FD.
