i just used a full spindle of the 50pack 12x 700mb PNYs myself, i got it during the after-thanksgiving day sale @ staples for $12.99. using a plextor 12/10/32a, i didn't get a single coster, and used them for various types of media. data cd and game backups worked perfectly, music cds read fine in cd-players, stereos, and car players. half of them went to backups of my dreamcast games, which are notoriously picky, and ran through perfectly. if you've had problems with the PNY cd-rs i'd be interested to know which cd-r drive you were using, and i'd be especially interested if you got a coster using a plextor drive. just another vote for the PNY, best value for cd-rs i've seen since the kingston packs from outpost =)
