I can't hear BenQ anymore. The BenQs are mostly old hats and very overrated, as Dee put it.
I would maybe recommend: LG GSA-H22N (and its successors), LiteOn LH-20A1P (chances are that some firmware upgrades may fix the bugs) - or maybe even the Pioneer 112 (but not the 111 anymore).
The 716s were very good drives, I just got one a few days ago
Maybe I'll get another one.
