I have the Harmy Despecialized BlueRays. I got them off Sideshow Freaks. The quality is marvelous! I'll admit, I was worried it'd be basically a VHS look on a BlueRay disk. They, however, are awesome! The picture quality is amazing! & the sound is really good too. They're so good that I DO NOT miss, nor have I watched again, the Ruined Edition (a.k.a. Special Edition) since.
Just seeing Han shoot first (& let's face it, Greedo never got a shot off), was worth it.
