The best answer is to check the CDs yourself. If you get a Plextor Premium burner it comes with error-checking software. Someone posted a link to a site that offers standalone software, but I haven't tried it. If you want to try it out I'll find the link and post it here. Another thing is to have decent burning software. I recently got CD Architect for that reason. I record local groups who send their CDs off for replication and it's common sense for me to be able to hand them a CDR and say, this one works.
