Who OEM's Pioneer A08's ? What brand name to look for?

Who OEM’s the Pioneer A08 or 108’s (new 16x model) ? I keep seeing great deals locally on generic brands (micro advantage, pacific data, mad dog, etc) but do not know who actually makes the drive inside.

Any guide for this sort of thing?

Generic brands don’t rebadge DVR-108’s AFAIK.

I’ve seen them only as PIODATA and MEDION drives.
