Go for LITEON LH-20A1P.Good DVD writer.I too have not yet faced any major problem with it except the Dual layer DVD problem.(U can fix it by firmware,so no probs).Also it supports 20x DVD writing.At Rs.1.5K,it's great value for money.I have burned around some 20~25 DVD's & around 200+ cd's on it.No probs at all.
