The NEC is a great drive, but the new Pioneer does 6X DVD+R DL, 6X DVD-R DL and is much faster at ripping movies. I think the Plextor is the only other drive that can do that, and the Pioneer is only $57.

People also say it's much quieter than other 16X burners.
Of course, by the time DL media gets cheap there will be a better burner you can get cheap, but at this point anything you get you'll probably keep a long time (since nothing will ever be faster than 16X and you'll use single-layer most of the time), so it's nice to have something that burns a full DL in a little under 20 min.
Those LightScribe drives are also a cool idea, except for the fact that it takes 25 min to do a best quality label (whereas my $90 Epson can label a disc in 1 min and do it in color).
