[moved] dru 720a /dru 800 question

what is the difference between sony dru 720a and dru 800 dvd+/-rw/cd double layer burner. Whats your opinion of dru 720a. Just upgraded from dru 510a to picked up dru720a for $69 at newegg.com

^^Same drive, different firmware. Only difference - the 800A supports -R DL burning. It’s an OK drive, but there are better ones to burn at 16X with, like the Benq 1620/1640, Pio 109, NEC3540 and LG 4163
