Of the IDE Sammsungs readily available in the U.S. right now I’d probably go with the SH-202G… but I have no basis for recommendation other than that it’s new, it has some killer manufacturer specs, and I haven’t tried one yet. Hopefully it will be fun to play with cuz it’s in the mail.
Honestly I’ve been looking for a drive to replace the Pio 111L and 112L as my main burners. I spent the last week juggling my collection and finally returned to the Pios as my best DVD burners. They don’t scan, and they’re poor CD-R writers; but they burn the heck out of a wide range of DVD media with nice PIE/PIF figures and consistently low jitter. My GSA-H42N posts better PIE/PIF figures but isn’t so good with DL media, and its jitter levels aren’t the best; my PX-716A and PX-760A can burn CD-Rs very well but produce unspectacular DVD results; my BenQs (1620, 1640 and 1650) are superb CD-R writers and can scan and overburn very well, but again jitter is bettered by the Pios; the DW2000/LH-20A1P burns better than my other Liteys but isn’t quite as good a scanner… and jitter’s inconsistent.
I dunno. You already have a well-rounded set of drives: the 111D as a great SL and DL DVD burner, the BenQ as a great CD-R writer, CD-R scanner and DVD overburner, and the 160P6S as a very even-handed DVD scanner. Buy anything you’ll have fun playing with.
