If I were going to buy one of the current dvd drives, I'd look for the 24x Samsung (which is getting hard to find) or one of the Sony Optiarc models, like the 7260 series.
Geeks.com has the Sammie: http://www.geeks.com/details.asp?InvtId=BLK-SH-S243N-BULK&utm_source=GoogleProducts&utm_medium=ShoppingSites&utm_campaign=BLK-SH-S243N-BULK
And it is also available through Amazon: http://www.amazon.com/Samsung-SH-S243N-Lightscribe-Double-Format/dp/B003YDZI6Q
The Optiarcs are available virtually everywhere, including Newegg.
The standard reply for good optical disks is TY or Verbatim. Look for AZO on the label of the Verbatim disks and don't buy their new "Life Series" variety. By the way, with modern drives and 16x media, you should burn at 8x, maybe 12x to get optimal results.
A third choice on blank dvds would be the Falcon brand media, made by FTI. You can find some at supermediastore.
