Thanks all for your patience. Rumors of my drowning in my own anticipatory sweat have been greatly exaggerated.
I'm very happy with the 747i thus far. The upscaling of SD DVD content is amazing. It even did a great job with the recent GOUT version of Star Wars.
Here's what I've got for now. I've found that it's pretty difficult to photograph nice images on a black TV in a really dark room, but I think there's still some good stuff here.
Thank You monoprice for an inexpensive but extremely sturdy wall mount:

Here's a shot of a NO SIGNAL screen. You may be able to see the egg shapes mentioned by S!TH. I find they don't distract during normal viewing...so far:

The SD DVD of CARS, output at 480i via HDMI from my Oppo 970HD. This film, as you might expect being Digital to Digital...Looks Incredible! (pun intended). My friend who came over to help me mount the TV exclaimed when he saw the CARS DVD, "That's got to be HD!" It really looks that good, this photo just can't do it justice. I might try for a better one later:

I haven't figured out how to get a good shot of the OSD yet, but you might be able to make out that the 747i is reporting a 576i signal. That's my R2 PAL copy of OLDBOY from the UK. I thought I'd give it a shot and yes indeed the TV will accept the true PAL signal without PAL>NTSC conversion. Nice bonus not mentioned in the posted specs:

A shot from tonight's LOST. So far the built in OTA antenna works very well. It pulls stronger signals OTA than my LG3200 DTV box did:

Looking through a window?:




So, there's some images. I haven't even really had the chance to tweak settings and such. I 've done a little, but there are so many more options to explore. I'm pretty pooped, it's been an exciting day.
Oh, and I can't comment as to the quality of the PS3 (I'd assume it looks amazing). I opted for a Wii:
