My close friend recommends the LG
over everything else we carry at our store, currently. It's supposed to be one of the best mid-range models for media compatibility, etc., and Newegg sells them in black, as well. As for Samsung, I only know they're a reputable company.
Doesn't Lite-On do a lot of manufacturing for Sony? I know the Sony DVD-ROM I bought was manufactured by Lite-On. I'm not sure about their DVD-RW drives, though.
I've been told that Pioneer manufactures the very best DVD-RW drives, but they haven't received perfect reviews on Newegg. Around here, Pioneers can cost $20-$30 more than the mid-range drives-- but not so on Newegg, so I don't know.
