Excellent piece of free software, BladeEnc, is now in version 0.90. BladeEnc is one of the best mp3 encoders in the world -- it's sound quality is just great. It loses in speed for most of the mp3 encoders, but the quality balances the situation a lot. And anyway, everybody has P2, Athlon, P3, ... nowadays.
