Which just goes to show.
I have the 2100E (IDE) and previously had the 8424 version. I have found both to be nothing short of very good.
Initially I had the vibration problem with the 2100 - I remounted it being careful to let it 'settle' in to a good spot on the rails and it has been fine. Sure, you can hear it is really spinning, but it does not vibrate anymore. Of course if you have a flimsy steel case or similar you're probably in trouble - but I had an old 52x CD-ROM (in an old steel case) that was much worse, so I think it is a case issue, not CD drive.
Not had any issues with reading other CDRs either - I do very frequently. Make sure they are not burnt using DirectCD or similar - you'll need to re-finalize the disk in DirectCD or get the discs burnt as closed CDRs...
Finally maybe yours is a lemon - if you really still have issues - exchange it.
