DVD PLAYER RECOMENDATION

I AM LOOKING FOR A DVD PLAYER THAT WILL DO THE LATEST FORMATES. I AM LOOKING TO SPEND NO MORE THAN $400 USED. I WOULD APPRECIATE ANY HELP I AM NOT TO SURE ON WHAT TO PICK UP. THIS DVD PLAYER WILL BE GOING WITH A BOSE ACOUJSTIMASS 16 SPEAKER SYSTEM AND A DENON AVR-1506 RECV. ITS NOT THAT GREAT OF A SYSTEM ITS JUST FOR MY WIFE.

THANK YOU
