Those Texas Chainsaw Massacre and Nightmare on Elm Street are pretty loaded special editions, especially for laserdisc. For a long time, those were highly sought-after by horror fans, as the initial DVDs had nowhere near the special features. Even as LD was dying or dead, those discs would still fetch a good price on E-bay. I think all the special features have been ported over now though.
