I recommend paying to upgrade to the Deluxe version. It includes CD Spin Doctor, a good program for recording and cleaning up music from phonographs or tapes. You load each CD into your Macintosh and drag the desired tracks onto Toast's window. You can arrange the tracks in any order. When you start recording, Toast will tell you when to insert each CD and will record the tracks in the order you picked.
Toast can do backups, but dedicated programs make backups easier.
I'm not as familiar with the Sony or LaCie CD-RW drives. You can download a specification sheet for a FireWire Yamaha drive. You can also try the usual mail-order and Web stores. MacReviewZone features CD burner reviews and links . For example, when I convert phonograph records to audio CDs, I first record the phonograph music onto my special partition using CD Spin Doctor.
