I have purchased previous volumes of these 2-disc compilations from Digital Sin, always finding them a worthwhile investment due to the sheer amount of variety included when it comes to the performers. They're like the porn equivalent of the old K-Tel collections on 8-track and cassette, with "the original hits by the original artists"! Wonderful companions when traveling for work as well. It would be too expensive to track down all these DVD titles individually in order to watch your favorite performers in action and this is also a great way to check out scenes starring performers with which you're unfamiliar.
