well never mind.
i ordered the NEC2500A becuse writeing quality is more important to me than dvd readability in a drive
becuse i have the liteon 166-s i have a fast and great dvd ripper drive
combined with a great dvd burning quality i should be fine.
i would have gone with the liteon if only its writeing quality was good rather than its awsome readability..
i hope i made the correct choice either way its ordered i cant turn back the clock 10 minutes lol
