Note: I hope this post is appropriate for this forum as it pertains to DVD ("software"). Since I want to calibrate my upcoming HDTV-ready monitor by myself, I am interested in purchasing either the "Video Essentials" or "Avia" DVD. I am told that while "Avia" is more expensive and complex, "Video Essentials" is cheaper and more user-friendly. I am unsure which of the two products is worth buying. Is there anywhere to purchase the DVDs online or off-line at bargain prices?
