Several questions.. thanks in advance for your attention and answers. rima carries 4x taiyo yuden dvd-r's for $0.90/50pk: http://www.rima.com/Merchant2/merchant.mv?Screen=CTGY&Store_Code=R&Category_Code=DMRTY Meritline carries 8x taiyo yuden dvd-r's for about $1.00/50pk: http://www.meritline.com/taiyo-yuden-8x-dvd-r-silver-thermal.html It seems like the price difference between the two is minimal.. Any reason to get 4x media besides saving $10 per $100? another question: Meritline carries Ritek 8x DVD-R's (G05) in shiny silver top and matte top with a rather significant price difference: 0.63 for shiny, 0.80 for matte, or $17/$100. Is the difference purely cosmetic? Here is the link: http://www.meritline.com/8x-dvd-r-blank-media-dvdr-discs-disc.html They are on the 3rd row of discs. It also seems that the pricing difference between Ritek and taiyo yuden is relatively minimal. Why would one choose one over the other? Also, what is a stacking ring that some spindles apparently come with?
