Thanks for the reply
I am in the UK and the BenQ 1620 Pro and the NEC 3540 are available to me. The BenQ 1640 isn't out here yet.
From what I have read, the BenQ 1620 Pro and the NEC 3540 seem to be the best to drives. The BenQ 1620 Pro seems to give slightly better burn quality but not by much (correct me if im wrong). The NEC 3540 has faster dual layer writing so I would like that but some people still prefer the BenQ 1620 Pro.
So thats what I am stuck between, the BenQ 1620 Pro or the NEC 3540.
Are both drives ready to burn at 16x (on -r media) out of the box or do firmware upgrades need to be done to make it have better quality burns?
