There's plenty of RIPers out there, but you can actually do it via winamp.
Go to Options -> preferences -> plugins. Choose the Nullsoft Disk Writer plugin and whatever you play with winamp will be saved as a file.
To save as a mp3 file, choose "configure" from the plugins directory after selecting the disk writer plugin.
Then click on "convert to format" and choose MPEG Layer 3 with the quality you want.
When all is ready, press play and the CD track(s) will be converted.
Enjoy!
