i just saw the post about a 50 pack for 50bucks. i know that people here have ordered -r's and they're good, but has anyone here ordered the +r's. i know that they're a bit more, but there are 2 of them and i don't know the difference.

one's a couple $ more than the other. does anyone know if they're as good a quality as the other ones. plus, do i have to worry about burner compatability? i have a sonydru510a. thanks
