I recently purchased Kosby's Impossible Card Magic on DVD, and I have to say that he floored me with his magic. Every card effect, and especially "Raise Rise," had me rubbing my eyes in disbelief. He makes Fred Robinson's "Ambitious Riser" move look ridiculously easy, until you realize it's ridiculously difficult with a deck in your hand.
Ray's "Oil and Water" routine is wonderfully deceptive, uses no "extra" cards, needs no table, no pesky Vernon wedge break, and is not that hard to learn.
Meir Yedid is to be commended for releasing these tapes, and many of those old wonderful A-1 Multimedia tapes onto DVD.
