I buy a lot of used DVDs and rip them to my media server. Being used a lot of the DVDs have scratches and other damage. So I'm looking for a DVD burner that is good at reading damaged DVDs at a reasonable speed. I'm not so concerned with features like Lightscribe or the quality of the DVD burns. Any suggestions? I've read that the Liteon iHAS424-98 and the Sony Optiarc AD-7260S are good drives.
