Thanks for response. That must be Amazon in U.S. where I am it lists it but far more expensive even for used copies. Besides I do not now own a video/VCR , would have to buy one just to play it; and used copies may be well worn the tapes were released in 1984!
Some people I'm sure have transferred it to DVD using professional service for best quality or even software at home, if anyone has it on DVD in good quality please message me.
Regarding Bikram suing Raquel, he did indeed and it was settled out of court; I heard too he won millions from it but don't think either party have said officially how much, etc - probably part ofthe out of court settlement to keep quiet about it.
From reviews Raquel's tape is meant to be exceptionally good, and does basic to very advanced material.
