Official DVD from Shout Factory
On December 10, 2013 Shout Factory is releasing the film as part of a cult movie collection with three other flicks. Shout Factory generally puts out quality releases... though all of the films in this set are full-frame, which makes me question if it's sourced from video (complete with the obtrusive microphones that frequently bounced into frame on the VHS release) -- but for $10 it makes the overpriced videos and rampant bootlegs obsolete.
