I have purchased a PC from Mesh Computers. The original specification included a Pioneer Blu-ray drive which was reviewed in PC Advisor as part of it's review of the Mesh Elite Storm HD. The blu-ray drive supplied by Mesh is an LG blu-ray drive.
Mesh have told me that the LG is of a similar quality to the Pioneer drive.
I do not know whether it is or not, but perhaps someone out there can advise me.
