Ive read that the Memorex +R are the RICOHJPNR01 by someone on amazon who bought it. They are both $85 for 100 with free shipping. Some people reported the Memorex burned at 8X. I have no idea if they would on my Memorex Dual writer, but it states it can do DVD-R at 4X and DVD+R at 8X. Any opinions on what I should buy?
