CDex Features:

CDex is an application that records audio tracks from CDs and saves them to a disk as regular WAV files or as encoded sound files. This program features an MP3 decoder (MPEG 1/2/3-based) and a new LAME encoder, and has built-in support to generate OGG Vorbis files. CDex is available in English, German, Italian, and Spanish. This latest release includes better support of USB drives when using Native NT SCSI library option and various bug fixes.

Functionally, one CD ripper is pretty much like another: They copy the contents of a CD. Still, each one has it's quirks. CDex however, lets you encode the ripped tracks as MP3's. Simply download CDex ripper and go.
