Which writer for best Dual Layer preformance?

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.

From the scans i’ve seen here i’d say Pioneer 112D. You already have the best discs to use unless you use MKM003’s which burn a little faster.

Edit:
If you are in the USA Best Buy has them as Pioneer 1810 but it’s the same drive.
