Recently purchased the BDP-51FD ($600).
Think the video quality is a notch below the Toshiba A35 HD player it replaced ($350 + 10 free HD movies on Amazon).
The 51FD has (sporadic) problems resyncing dialog to the picture when slow-motion is used.
The 51FD is quieter (cooling fans?) than the Toshiba.
Finally, I've noticed my Samsung LED DLP TV making LF noise switching from scene-to-scene.
I'm not saying the Pioneer is causing this, I just never noticed the noise with the Toshiba.
