Seems pretty good, but all I can find on the developer's website is a beta version, which appears to have been in development since March 2007 and still costs $15. Why would I pay the developer to test his software for him? As other reviewers noted, there's little documentation and the app isn't entirely intuitive.
For payware, I'd recommend MyCoverCD or CD Labeler as inexpensive apps that get the job done; I've tried both and prefer MyCoverCD's GUI and feature set. For a bit more cash, my favorite is Disc Cover - I've been using it for years and it absolutely rocks. Its got a rich feature set, a wonderfully intuitive function, rock solid stability, and the developer updates it regularly to keep pace with OS X. Another benefit of Disc Cover when compared to the cheaper shareware labelers is that a lite version ships with Toast Titanium, so it has a broad user base as insurance against it becoming abandonware.
