Best Blu-ray/DVD player for under $800?

Lexi[CON] BD-30, I mean Oppo BDP-83... I kid, I kid.

Seriously, from my list below, which Blu-ray player do you think would offer the best BD picture quality with a 1080p plasma via HDMI, as well as the best possible rendition (upscaling) of SD DVD's? Audio is not such a concern as I only use the supplied L&R speakers at this time.

The list:

Denon DBP-2010CI
Marantz BD7004
Oppo BD-83
Anthem BLX 200
Pioneer Elite BDP-05FD

and just to mix it up;

PS3

Note: The Oppo is the obvious choice for many because of price, but consider the other BDP's as "open-box" or "preowned/demo" priced for comparisons sake. I won't be paying full retail.
The PS3 is thrown in because many seem to think it ranks up there with most mass-consumer BDP's on the market. I might agree with that at it's price and below, but not against $800 stand-alone BDP's. The plus side: games, as well as access to Netflix and Amazon VOD.
Sony, LG, Panasonic, and the like just don't seem relevant IMHO. At first, I considered buying some subpar <$200 BDP, but I can't be that cheap. Not with a 1080p plasma. What's the point. I've tried those lighter-then-paper weight DVD players and the picture quality was very poor. But then again, how can they compare to the only other DVD player I've owned - Meridian G98 AH. I just can't justify, nor afford, spending that much again on a component used solely for playing DVD's, as incredible as it was. Maybe when they make something similar for BD playback in the $2500 and less range.
I also consider buying a higher-end discontinued model (MSRP $2K, now discounted to less then $1K), but with how fast these products become obsolete (no network/ethernet,..), I'd rather get a current model.
And as mentioned above, I'd like having access to Netflix, Amazon VOD,... as well, but unfortunately only the subpar $200 players seem to offer this feature.
There is also one detail with a few of the BDP's in my list that bothers me; the small, cheap, two-prong AC input. Why?! It makes no sense on a $800 player. That can always be upgraded though.
