Professional CD-R and DVD-R Burners/Duplicators?

burnWell asks: "I work for a software publisher, and when preparing CD media for final distribution to the manufacturer (the Gold Master if you will), we often find that our CD and DVD burns are not very good quality. Are there any recommendations for professional grade, highest quality CD-R and DVD-R writers? Are there any tools or metrics we should use to verify how 'good' a particular burn happens to be, and to that end, how well behaved some brands of media are versus another? Are there recommendations for the very highest quality CD-R and DVD-R duplicators?"
