Best used DVD Player...Not interested in Blue R...

Could anyone recommend me a good DVD player in the used market. $400 to boot. Not interested in Blue Ray blah blah....or anything like that.

Need good picture, good sound. Mainly for watching movies and concerts on my 2 channel Rig. Considering Sony DVP9000ES or something in that league.... will be using it as a DVD Transport for everything mainly.

Any suggestions will help. Thx
