Ok. The NEC can have reading issues where small scratches and smudges can potentially cause reading errors.
So buy a nice DVD-ROM (Lite-On or Asus) and the NEC should be able to give you great write quality.
Plus DVD-ROMS are generally faster at ripping anyway and are cheap. ($35?)
The LiteOn 812S is just arriving in stores now as well. I haven't found a review yet. But judging from what I've seen it will be the best LiteOn DVD burner yet.
Those would be my two choices personally.
Take the time to read around before buying your burner.
