Meaning saving a few bucks on a rebadge or the like is a bad idea imo, buy a retail drive.
So your saying buy a retail BenQ with OEM fw Bitsetting suppot?
I'm have trouble with parsing these, so please excuse me if my responses don't seem to be all that responsive. Furthermore, I may be mistaken in some of my opinions. If so, others will correct me.
First quote: Rebadge and retail are not true alternatives. For example, one can buy a retail Lite-On DVD-RW that says Lite-On or one can buy a drive that says Sony or Memorex, both of each are sold as retail rebadged Lite-Ons. You won't save money on either of these rebadges, both generally cost more that their Lite-On cousin.
Second quote: I don't get this one at all, anyway, here goes. OEM fw support does not "come with" a retail BenQ in the context that such support is not in the box. One may obtain FW updates from whoever is on the box or other enthusiast sites such as: http://dhc014.rpc1.org/
. One possible disadvantage in rebadges is that they don't usually pass through all the FW updates that the "real" OEM issues. AFAIK, booktyping/bitsetting allows burned DVDs to be played in older DVD players that can't otherwise read these DVDs. I don't think that my NEC ND-3500A supports booktyping/bitsetting, however, it doesn't matter to me as my DVD players are less than two years old and can play my movies "fair use" copied onto DVD+R media.
Lastly, about OEM version versus retail:
If you don't have screws, a cable and software; don't want to bother with obtaining software elsewhere; will be content with any bundled software then buy a retail package.
If you have screws, a cable and software or don't mind getting them elsewhere and want to save a few bucks, buy OEM.
Further note: my NEC ND-3500A, purchased as an OEM version, did come bundled with a "lite" version of Nero (i.e., Nero Express).
