Looking for recommendations re a used single play DVD player? Will be useing it for watching movies and "concert" dvds in two way JBL system. Present dvd player is a low end model. I have a decent cd player that I'm very happy with. "Older" high quality model would be prefered as long as it has competent progressive scan, good audio and optical audio output. Don't want to sink a fortune into a new dvd player at this point.
