Ive always had good results with pioneer dvdrw drives
a friend of mine is a naughty lad and is always writing dvds and he's been using a pioneer for years and its never let him down. more important is the type of discs you use, Ive always used -R discs that use the Ritek dye, as they seem to be very reliable and compatible with anything i want to use them on. lightscribe i think is a cool idea, but you can only print in monochrome, I use an epson printer that can print in full colour onto printable dvdrs in photo quality, they look very impressive.
