Where can I see the Richard Lester version of Superman II?

I'm a little behind the times. I wanted to see Superman II online after hearing about its plot - mainly, the part about Clark "burning" his hands in the fireplace. But I can only find the Richard Donner version online. It was great, and I watched two of my favorite scenes about five more times before finally closing the window, but I'd like to see the Lester version as well. The problem is, I can't find it, which I find odd seeing as how the Lester version was the original theatrical release of the movie. Can anyone point me in the right direction?
