Cheapest good sounding dvd player?


I want to watch and listen to some concert dvds but my little player produces very poor sound. What do you think is the cheapest available dvd player with better than minimal sound quality.
I do not need any 'features' beyond stereo rca outputs and rca 3-line video outputs.

If you can find a good used Marantz DV8300, DV8400 or DV9500; Denon DV5900,5910 or any in that series these are good sounding and play SACD and DVD-A as well
I asked about the CHEAPEST machine with "better than minimal" sound quality.
I am not seeking "the best cheap unit." I seek the cheapest "good" player.
Even used, OPPO units cost a few bills.

How about this:
What's the best player I can get for under $150.
