I'm about to buy one too.
I'm interested especially in the best writing quality possible, especially with verbatims 16x (+ or -) no matter at what speed, and of course durability (my NEC ND-3520A after a year of light/moderate use is getting worse and worse at burning...).
I've narrowed my choice (am I right?) to Pioneer DVR-111D (not 112D, I've seen not so good scans so far), LG GSA-H42N or H22N, and Lite-On LH-18A1P.
Any suggestion, even on new drives to come, would be greatly appreciated, thank you!
