You can get a good Onkyo or Denon (quality consumer brands) DVD-Audio/Video player for about $200. It would be worth it even if you don't have surround sound (5.1 receiver and 6 speakers), because 2 channel stereo DVD-Audio is still amazing. Careful, some players will only play DVD-R and not DVD+R. You may want to wait to buy a new standalone player until the format war that is currently going on between HD-DVD and Blu-Ray is over and a winner is declared. Then buy a player that supports DVD-Audio. Commercial discs are about $15, the same as CD's, but there are a lot less titles available. You can browse DVD-A titles at www.circuitcity.com (lower prices) or www.jr.com (more titles). You can also burn DVD-Audio discs from 24 bit FLAC files with free software available at:
