IT IS NOW AVAILABLE ON DVD ON AMAZON -DOT- COM!!!
I just got my copy in the mail yesterday. It's actually a DVD-R copy that they burn when the order is placed, but the quality is excellent - probably better than VHS. Keep in mind that the movie was made in 1975. I paid about $12 - much less than they're selling used VHS tapes for.
Go there and get your copy today, before they change their minds!
