I'm looking to buy a new DVD writer and make a lot of Dual Layer burns. I'm very concerned about the writing quality so I only burn Verbatim MKM001's on 2,4 speed. Which writer has the best performance on Dual Layer media? I was thinking of buying a Liteon LH-20A1X drive. Would that be a good choice or are there better drives? I don't care about Lightscribe or Labelflash, only Dual Layer quality counts for me.
