LameBrain is a freeware LAME GUI for Mac OS X. It comes with single and batch file encoders, as well as a CD Ripping tool with FreeDB integration. A LAME binary for OS X is also included, but you can use your own version if desired.
The current "stable" version of LB is 0.5.2, and can be downloaded from:
