I have looked hard at the 929, just a couple random thoughts.
I have seen the 60" Elite for about the same price as the 65" 929 so if you were looking at the 65" 929 there is not much of a price difference.
The 65" 929 has a really thin Bezel, in terms of over all size it's not much bigger than a lot of the 60" sets you might look at because of this fact.
The 945 is what I was hoping for I really want a 70" and the 70" Elite is just more than I can spend it it were maybe $1300 less I could likely swing it. With all the rumors swirling that the 945 got cancelled I am not sure what to do myself.
The 745u/7450u are still an unknown quantity, the one I saw at Frys did not have the dark corners issue of the 735u, uniformity looked fairly good and I did not see any obvious DSE, however I did not have control of the source, and the 2 sets were seperated by about 100 feet, one was under direct lights, and one was in a darker area so it's really hard to compare.
My biggest questions about the 745/7450 sets are the Black Levels and Viewing Angles, if those come up comparable to the 735u, It's likely I will grab one as my next set.
