Please let me know what you think about this Plextor - L890SA? I need a slow burning drive with the PlexUTILITIES for mastering. This one comes with it and it's not expensive. i know that a slow mastering burning at x2 or x4 is good, this one i'm not sure if it goes below x8?? Can i use this Plextor? Can anybody recommend or help me with this?? Thank you for the help!
