Most of the negative comments are off, at least not with the 72x.
<<They are poor readers that slow down tremendously on most CDR, and only play some CDRW.>>
Thats been a problem with their 40x and 52x, the 72x does not suffer these problems, not nearly as much as the older generations. The newest firmware handles the CDR/RWs impressively, not quite perfect but very good.
<<Half the time mine slows down on some factory pressed CD's.>>
Unless you've been brutally abusing those CDs, the 72x should have no problems. None of my factory pressed CDs were having problems with the 72x.
<<Their own benchmarking program shows that they are cpu hogs, and suck at audio extraction.>>
I dont know where you pulled that out of. This is one of my examples, with my old Acer 40x, when I insert a CD and it starts autoplay, my MP3 player will have to pause until the Acer finishes spinning up, the 72x autoplayed in a breeze and my MP3 was never cut off. The audio extractions, when the 72x reads the CD fine its usually multiple times as fast as typical 40-50x CAVs.
<<I wouldn't dare burning drive to drive from my 72x, I found out about it too late. In many cases, my old Acer 24x was better. There is a review site that did an excellent job of reviewing it, but I lost the site.>>
I use to worry about that too, but after all the 72x impressions, I will not have a doubt about burning a CD from the 72x.
Further more, the 72x is completely silent comparing to most typical CAVs, even reading at optimal speed its still quiet. If you ask me for a CAV recommendation, I'd say go with TEAC 40x or Toshiba 48x.
