Used these before and seemed pretty good, cheapest I can find.
Aone 8x Full Face Printable Dual Layer DVD+R DL in Packs of 25 are manufactured by Ricoh and branded under the up and coming Aone brand name, this disc has set a new precedent in Dual Layer (DVD R DL) pricing. An amazing price for users who need some affordable dual layer discs. Also known as double layer, these discs have an 8.5GB data capacity, equating to 240 minutes of video in standard play mode.
Inkjet printable discs such as these enable you to add your own designs to the top surface with affordable machines such as the Epson R220 and R300 inkjet printers. Combine that with the ability of dual layer discs to hold nearly as much data as a commercially-pressed DVD and you have the ability to create high-spec movie and data discs at a bargain price!
