I really don't use cdrs anymore since getting a h120 for flac playback in the car. archiving is all done on TY (or made in japan sonys) dvd so I don't really worry about TY cdrs as shelf life of audio cds isn't a concern for me anymore as there are backups of everything I have on audio. when I do buy cdrs I get TDks from target or wherever they are the cheapest. usually $8 for 50 spindle.
