NEC and Plextor are the most recomended (and Plextor is the better of the two, but pricier). Plextor also has top-notch technical support if ever you need it (they replace their drives for free).
Lightscribe is a "fluff" feature that nobody needs... it's also pricey (you need special disks).
If you're on a budget, go with NEC... if you want top of the line, go with Plextor.
