Well right now I have the NEC 3520 (1.UG FW) and the Pioneer 109 (A09 Crossfaded 1.57 FW) DVD Burners. A friend of mine is giving me the option to switch out one of my two burners in exchange for a brand new Benq 1620 Pro. Should I trade him one of mine? If so which one should I trade for the Benq 1620 Pro? Any of you who use any of this drives recommend me what to do ?
