I've heard that some Imation CDRs have turned out to be manufactured by Taiyo Yuden, which would easily rival Kodak in quality. Try looking on the outside of the Imation box/spindle for Made In Japan. If it's not made in Japan, it's probably not Taiyo Yuden, and in this case, or if you can't inspect the container before buying (i.e., online vendor), I'd get the Kodak blanks.
