One should be careful before slagging off a company as this is common now with most companies - Cutting costs cutting corners, things are NOT built the way they were, I can say this out of experience - I go through testing a lot of things and notice it.
As to BenQ, isn't that ACER ? I owned a few of those a while back and they broke down quickly. Garbage - but then again we maybe end up with a bad batch which does not mean all BenQs are crap. I have read about the same things happening with LITEON (same quality control problems) they are EXCELLENT burners if you end up with a working one, luckily I never had problems with LITEON.
