Ktech Hypermedia CD-R's at Outpost,,, I have gone through a fifty pack of 8X 700MB discs. They are nice looking, but I have already had one go bad after about three months. I haven't tested all my old burns bot that's a little disturbing. The discs are made by CMC Magnetics, and are definitely a low end disc. I personally recommend TaiyoYuden (They make Imation Golds) or TDK. I don't have a lot of experience with some of the other brands, but keep in mind that 5 or 6 plants make all these different brands of discs.
