Great feeling isn't it?
I bought some $2 dvds from Go-Lo that were called Rockthology. Only managed to find a few volumes, but they has some interesting stuff on them. Like an interview with White Zombie around the La Sexorcisto era, and a few interviews with Halford and Priest. Ozzy, Exodus, even a band called Vio-Lence which I recognised Rob Flynn and Phil Demmel from Machine Head in the band. Great stuff to watch. But the best is anything with God aka Lemmy, he always tells it straight, no BS from him.
