Please help.. I'm wondering which one is the best, in terms of compatibility, the ability to read and burn all type-s of CDs and DVDs, and offcourse, the burning speed. Reliability is the most important factor. 1. DVD+RW/-RW Pioneer DVR-108, Dual Layer, 16x, bulk 2. DVD+RW/-RW NEC ND-3500A, 16x dual layer, bulk 3. DVD+RW/-RW Liteon, DL, 16x, bulk 4. DVD+RW/-RW/RAM LG GSA-4160BB, Dual Layer, 16x, bulk 5. DVD+RW/-RW Gigabyte W1608A, Dual Layer, 16x, retail 6. DVD+RW/-RW TEAC DV-W516D-002, 4xDL, 16x/16x, bulk It would be best if you could make a "rang-list/top-list" of all these models based on your experience, and also because I'm not sure if all of these drives would be available in my country during the holiday season. Thanx in forward!
