To be really frank , if u visit sites like cdfreaks or cdrlabs .. people say that benq is king .. i got benq 1640 , lite on 165p6s and lg h10n ..
out of these three .. lite on rocks .. benq is excellent on + r media but poor on -r media .. tried 8 different firmware .. still the problem exists ..
and i just recently got lg .. hence can't comment on it ..
