Ditto what John said (and not because I sell them).
I spoke to Mike just before he left for yet another filming trip. The DVD's are going to be quite some time in coming. He has a
ton of other projects on his platter (he's definately an other-achiever!

).
Each video builds upon the other without actually being serialized. And of course the newest ones use the latest video tech, digital, etc.
I have a preference for
Striper Magic as that was the first of his videos I saw. But they're all great.
