BenQ is basically Philips and/or LG Electronics.  They use a lot of the same OEM stuff.  Their DVD-Burners are rated as some of the best around, in fact the new Plextor Anand just reviewed is just a BenQ burner.  So you made the right choice with that since its about half the cost of the Plextor.  The NEC burners used to be better, or at least as good depending on who you talked to, but I think BenQ took the lead with the latest round.  Their Projectors are awesome because I have one, and their LCDs are very good too.  Some are better then others, the one your talking about is very good.
Overall they make some very good quality stuff.
