Personally I have good luck buying cheap media...I by bulk 100 CD spindles from Canadacomputers.com for $25 canadian....Mr Platinum i think is the brand...for just music CD's or anything...I use them
but for more important data, such as backing up accounting info, I do buy a 10 pack of TDK or Mitsui CD's from Walmart once in a while for that stuff....CD's are more durable and will probably last longer. I recommend TDK or Mitsui
