I haven't seen it myself, but there's a decent HDTV > DVD bootleg floating around called Rad.1986.NTSC.HDTV.DVDR-CMG
Here are some others I'd like to see on DVD
Once (1971) - mysterious and elusive experimental film with great soundtrack

Sea of Joy (1971) - Australian surfing doc
Last Summer (1969) and many other
Frank Perry films

LAST SUMMER is one of the most highly requested titles in our vast library, and we planned to make it available last year when we launched the Warner Archive Collection. When we were unable to secure a good quality master which retained the film's original theatrical aspect ratio, the release was postponed. Fortunately, the issue is resolved and we look forward to announcing its DVD premiere later this year.
American Dreamer (1971) - perhaps Hopper's best work
American DreamerPretty Maids All in a Row (1971) - it's better than a lot of Vadim movies already on DVD, written by Gene Roddenberry
Phantom Tollbooth (1970) - kiddie classic
World's Greatest Sinner (1962) - greatest independent movie ever
(TCM sourced DVD-R is on thepiratebay)

Michael Mann's
The Keep often gets mentioned in these types of threads, but the movie isn't very good
