Toei has released this movie to Discotek.com: Master copy, widscreen DVD

Toei is the animation company who made this movie. They have given the rights over to Discotek and it is now for sale here: http://www.discotekmedia.com/the_little_mermaid.htm

This is it. The original movie in all its glory. $19.99. The clearness of the animation is striking, I love it! Youtube videos PALE in comparison to the crispness, line art, and color.

Discotek is a well known company in the anime market known for buying the rights to older animes and providing them for sale to the West. It's official! I can vouch for the quality and trustworthiness of the site.

It is also interesting to hear the movie in its original Japanese language, with subtitles.
