Pico, I'm currently in the process of preparing a site just for that purpose. I'm slowly collecting samples of major brands and doing some in house/store testing. Since most of my tests are done with LiteON and Plextor burners, it may fall into your interests! please e-mail me if you would like to help. It's sorta my pet project, but I have zero talent/knowledge of web design, and extra input is always invited!
I plan to test a new CD-R/W every two weeks (cause that's when I get payed

). I will happily take requests. So far I'm working with a CD-RW made by RiTEK, branded SAMSUNG DIGITall. It's certified 10x but burns quite well at 12x! it's 650MB, and so far it is doing quite well in my testing. Pics from Nero CD Speed, Disc Doctor, and eventually WSES will be available, as will my personal opinions on the Disc.
