Tough to say, BenQ used to be a no-brainer, but "Elvis has left the building"... LITE-ON snatched them up and in my opinion have not produced a burner worth a damn.
There is always Plextor, but they are pricey and LG makes an affordable burner that I am growing fond of (unless you do CD+G). For me, I am waiting for the Plextor Premium II to arrive in America for CD burns... LG is a good DVD burner and if you want to do scans, get a LITE-ON burner to do those... I have yet to try a Pioneer drive...
For now, I am running a Plextor PX-716A, a BenQ DW1640, and a LG GSA-H10N... I think the H10N is the only one you can still get and it has been replaced by the H12N... MP3Mogul, another member and mod here at CDRinfo.com picked up an LG GSA-H22L and has sung its praises... It, too, is a newer model based on the Panasonic chipset and does 18x speeds faster than any other... LightScribe does not interest me.
Get some opinions, read the forum and industry reviews (avoid cnet) and make a choice... Heck, another NEC might be okay.
