I've not seen such a list, one of the reasons is that many brands switch manufacturers very often.
TDK for example have a 8x4 that may be a plextor but they also have a 8x8 that is a NEC - and there may be others as well.
There is not many Plextor rebadges - probably since they are quite expensive.
What's wrong with the NEC? I think it's better value for the money than a Plextor....
