No need to apologize, I did cut in without posting any helpful info after all
I may be a little late to the game with this as the poll has closed so i'm guessing you may have already made a purchase but here goes:
I'd go with the Sony over the Samsung you posted as even though the Samsung is a higher end model there we're some serious problems with it for some people from what i've heard.
A good alternative to the hx729 that has good expert reviews is the hx850 (decent 3d performance, max might be 60"?) which is a very good edge lit. If you can find an hx929 for around the same price definetly go for it over the edge lit as i'm not sure you can get the edgelit in 65" .
Samsungs es8000 from this year may not be a better buy than the d8000 from last year: http://reviews.cnet.com/flat-panel-tvs/samsung-un55es8000/4505-6482_7-35118272.html
You could also look into lower end models without sacrificing much but you might lose local dimming on anything lower than the es7100 and d8000, 3d and picture quality on the eh6000 and you'd have to find them in the size your looking for (es7100? es6500, eh6000.
Samsung also appears to have the best 3d performance in 2012 for led lcds.
The current Samsungs seem to have less dynamic dimming issues but also lighter blacks as seen in this review of the eh6000: http://reviews.cnet.com/flat-panel-tvs/samsung-un46eh6000/4505-6482_7-35159621.html
and the review of the es8000.
You could also look into sharp for a big screen but I don't know much about them other than their full array sets start at 70" they're dirt cheap, have matte screens for good bright room performance and black levels are probably on par with this years Samsungs with lesser uniformity on sharps edge lits (and there is a big difference between the elite and regular sharps with the elite being the best lcd ever made).
Summing up, quality is all over the map for edge lit leds and the only company that seems to be able to put out a decent edge lit with deep blacks, no dynamic contrast issues, and good uniformity is Sony and plasmas in this price range (or even lower) do beat them for picture quality.
All of the sony's and Samsung's ive listed have glossy screens as far as i'm aware of and may not actually do much better than a plasma with a good anti reflective filter like the st50 or pne6500 in a bright room.
EDIT: I guess the poll didn't close, i just wasn't logged in
