Connie and Jennifer,
I get my Beta-Max tapes at the same place where I purchase all of my eight-track cassettes, the world famous "Uncle Steve's Electronics Store," located on Canal Street, just east of Sixth Avenue.
Perhaps you've seen Dan Ackroyd parody one of "Uncle" Steve's radio commercials, in that thick Hungarian (?) accent of his, on an old episode of "Saturday Night Live": Panasonic Hi-Fi VCR -$79.99, Nakamichi High Density Cassette Recorder - $109.53, Sony 50 inch Trinitron Stereo Monitor - $189.67. I love you!!!"
Bob the Bartender, who always "frugally" sets the VCR to the long-recording "EP" speed.
