Depending on what your going to be using it for. If it was me I'd grab the freeware stuff first. I burn all my video & data DVD's w/ ImgBurn, & DVDShrink 3.2 is an excellent if old dvd video program. CD Burner XP Pro is a good cd audio burner, but ImgBurn is going to have that feature soon. I personally only use Nero's scanning program, CDSpeed. I'm not kicking Nero, just saying there are excellent alternatives.
