There's a big difference between merely winning test score comparisons vs. quality of construction.
The Lite-ons are decent drives, but quality-wise they don't compare to a Plextor. Plus, Plextor always seems to push the envelope/add on thoughtful extras ... things like a cooling fan. And back in the day when the first CDe's, CDi's, etc., were hitting the market, a Plextor drive was about the only drive that was capable of playing all formats ... Plextor was constantly tweaking/writing drivers as new stds. appeared. When a company goes to the trouble of writing a special driver for a single specific CDe (ie. enhanced CD) so that it will run properly, you can't help but be impressed. Such was the case with Todd Rundgren's "The Individualist" which was one of the very few decent CDe's ever released. Compounding the situation was that it was developed for the Mac, yet Plex got it working under Windoz.
