I'm with you guys, I love this drive so much. Very fast and stable ripper with MSCE, and every single burn I've done so far gets excellent scans. I frequently get burns on ty02 with only a handful of PIFS, and none over 1! Even better than my NEC 3500, which I almost thought would be an impossible mission . I only burn at 8x anyway for best quality, and 8min is fine for me, so I don't really care much about the overspeeding thing.
I kinda like this drive better than my 1640 I think, for reading anyway it seems more solid. For burning they are very close. Maybe future 1640 firmware will change that. I haven't even tried lightscribe or loaded the software. I haven't really checked, but I'm thinking lightscribe discs cost a little/lot more? Same reason I've never bought a DL disc, I can't see spending $6 for a single disc, especially when so many ppl have big problems burning DL.
