If you don’t mind using the command line and having Fink or Darwinports, I can highly recommend mp3splt to split MP3 files. Best of all, it does not recompress.

Just name your source file, then a list of split points (in minutes and seconds), like

mp3splt my_source_file.mp3 0.00 2.41 6.14 8.33

Do it directly in iTunes, either destructively or non-destructively. CMD+i on the track in iTunes, under the options tab, set in the and out points. Do make it permanent, right click the track again, and convert to MP3.

It’s even easier to use some of Doug’s Applescripts for iTunes. There is a great script called (something like) “Copy from Start to Stop” which makes a new mp3 from any mp3 in iTunes, based on the start and stop times you set in “Options”. Along with another script called “Set Player Position to Start or Stop,” you can easily play the mp3, set the start and stop points by ear, and then make a trimmed copy which automatically shows up in iTunes named however you want. I don’t think there is encoding/reencoding going here, but I have never noticed a degradation of quality. See http://dougscripts.com/itunes/

I think if you are trimming an mp3 file, you are using it for a ringtone or some other one-off purpose, you’re not going to be hurt by the quality loss of re-encoding.

what a bad idea to re-re-encode a file…
I do not support
