It's free on YouTube. It's pretty good, and they managed to not use any of the riffs from the mst3k version, so it's almost like a whole different movie (except, of course, that it's still Manos.)
Part of the reason I like the black & white movies are because I saw them first on Saturday afternoons when I was a kid. Seeing them get riffed reminds me of being 10 or 11 and making fun of them with my friends.
