It appears the basic company philosophy is at least more dedicated to putting out a better product than Plextor (at least factoring in the price) is one reason why. I certainly can't disagree with AlexNoe about NEC, as NEC typically has had a solid reputation as burners.
Plextor used to be VERY concerned about its reputation, and worked hard on the quality of their burners. However, my reading indicates that stopped around the introduction of the 712/716 line. Whoever's running Plextor now really doesn't care to back up their product, nor make it like they used to. Sure, they could turn things around and improve--but only if they wanted to--and there's no indication they want to. :eek:
