Plextor. Not because I’m a Mod for this forum but the Plextor package and support is excellent. I have no experience with Yamaha’s support as I said and their package is good: one CD-R/RW and a good manual. The Lite-On package, well, sucks really. Manuals could be better, not much software, Ultra-Speed CD-RW disc doesn’t work at the speed the drive supports (based on my experience with the Lite-On LTR-52246S and the US-RW that came with that. The disc was just not good and my Plextor also couldn’t write it. alexnoe had the same experience).
Plextor has the best package. Again I’m not saying this because I am the Mod here, it’s a fact. They include 5 CD-R’s, 1 US-RW (which actually works at 24x), PlexTools software, good manuals and a two year warranty (Yamaha also offers this, don’t know about Lite-On). The Yamaha comes second, Lite-On on the last place. But on the other hand: the Lite-On is the cheapest drive, followed by the Yamaha and then the Plextor.
