Disk Copy will do it significantly cheaper. Put in the CD. Open Disk Copy (/Applications/Utilities/Disk Copy), go to File>New>Image From Device, select the CD and click OK (or select or whatever it is). Then set your Desktop as the save location, name the image the same as the CD name and click Save. After the CD is saved, eject the disc, and put in the blank one. When the error message comes up, click Ignore (or, if you closed Disk Copy, select "Open Disk Copy" at which point it will open Disk Copy, and, IIRC, prompt you for a disk image to burn. Select the disk image you saved and click select or whatever it is. If I'm wrong about the prompt, just follow the rest of the instructions.), and go to File>Burn Image. Select the image, set the burn settings, and click burn. Voila. One Copied CD (and you can make more copies of it more easily this way)
