Free YouTube to mp3 converter

Hello, if this post is in the wrong forum please feel free to redirect. I've been looking for a safe way to convert YouTube videos to mp3 files that can be stored and played back on my iPod. I used to use a program from DVDVideoSoft when I was on my old PC that worked fine, but they don't offer a Mac version. I've seen a slew of converters out there when I did a search, but I have a problem downloading anything from a site that isn't written in correct English. Anyone out there have any luck with this kind of freeware for the Mac? Thanks!
