are there any manufacturers out there that sell unbranded cdrs with a standard(silver) writing surface and black tops? I've been looking for them but the search always gets muddied with black writable ps2 style cdrs. I'm also looking for the writing surface to be as close to a professional look as possible(more silver, less green/blue). Other colors would be fine too, I've seen them in orange, but black is preferable. Any help or direction would be appreciated. Thanks.
