I've got something that does that.

It cost £25 (GBP) and included a little pressy thing that puts the label on the CD nice and straight.

Cool as!

Labels are pretty cheap as well. You can get some nice coloured ones or you can buy plain white.

It is, unfortunately, pretty clear they are labeled. If you want it written to the CD itself, you may have to do this at the CD manufacture stage. Cheap, if you're doing loads - expensive otherwise.
