Need advise on dvd player

I am basically a hardcore 2 channel guy. But would like to add a good dvd player to my current system. Current applicable equipment consist of...Cary Int Amp, Marantz SR18 HT receiver, JM Lab Electra 926 mains along with JM Lab Center and Surrounds. Need to add a decent DVD player keeping in mind I don't watch that many movies but would like a good experience when I do. Have always bought used stuff off the Gon with satisfaction. Need to keep price around $500.00. Greatful for some direction here.
