Best Standard Def DVD Player under $8,000 used?


I am looking for the best possible Standard Def DVD player
that is BLACK. I have a Krell DVD Showcase now and it's
great but I am wondering if there is better to be had for
under $8,000 used.

I would like to hear opinions/comparisons of the video
quality for:

Krell DVD Standard
Linn Unidisk 1.1
Meridian G98
Denon 5910CI

Thanks

I recently swapped a Classe DVT-300 transport out of my system (off for some repair work), and in it's place, bought a Sony BDP S5000ES BluRay machine (thought I'd try out the format). What a disappointment! The Classe blows the Sony out of the water. Its upsampling to 1080p is easily as good as the BluRay player. And the picture is more sharp, more vibrant. The Classe is beautifully built, the Sony looks like it came from Best Buy. The audio is no slouch, either - coax out to EMM Labs DAC2. There's nothing wrong with DVD playback on a good machine.
Dude! Hush up, I'm trying to hustle up some change to buy new stands and cables.
lol, I got some cable from a nice guy in a white van for sale......they say they go great with Theater Research speakers!
Theater Research speakers . . . do they handle 500 watts per channel, have 8 drivers, and the best vinyl cladding this side of a Payless shoe? I bet their greater than my Martin Logans. About the cable, sorry, I only buy cable from Best Buy.
