I have checked the offer of NEC DVD/RW Slim-drives and there a pretty much different models available.
The often recommended Sony NEC Optiarc AD-7543A ist about 40 Euroes.
I only need a reliable silent DVD/RW-drive to burn Data-DVDs, or 1:1 DVD-copies and normal Audio CDs.
Is there also an older comparable model available, which also does a proper job and is about 20 Euroes?? I don’t need things like Labelflash and those gimmicks.
