I don't know about still maintained, but it's one of those pieces of software that did one task, did it well, and the one part you might want to update (the encoder) was a plugin. As such, even though it's not seen any significant update since 2004, it's really the only CD ripper I've ever used. All the way back to some old Pentium machine where ripping and encoding a CD to MP3 took longer than it would to play it. Though the times I've needed it in the past few years has dropped off considerably, and if I had to rip a CD today I'd actually have to boot up an old machine that still has an optical drive.
