TDK (DVD-R47FCB50) 16x Spindle (50 Pack)

I've been using the -R version of these for a couple years. I burn at 8X with an NEC burner. I've had maybe one coaster, if that, in this time. I use silver Taiyo Yuden for especially important projects. But these TDKs work fine for every day use. And the price can be beat.

You may want to look at the reviews at Newegg, where folks seem to have had a similarly good experience with these disks.
