You could wait around and see if FX or Fox Family Channel reruns them, usually around Halloween. For a couple years, anyway, they'd do a whole week of them.
They are, however, editted in some form. I have all 5 on tape, and a couple of the shows have stuff missing. One the first one, Tom Mullica shows up to teach a trick, but his performance isn't there. And my copy of no. 5 clearly lists Goldfinger and Dove on the program (in the opening), and I remember seeing the performance when it first aired, but they're not anywhere on that tape.
