Ok, I was ready to buy, now I don't think so. It looks like the Handshake issues are being resolved, but I see that motion blur could be a problem (not good for sports or action movies). I see that the Oppo 981 may have problems with this unit (I own one). I see that Method just upgraded to HD and his SD went to hell (I have Directv HD with HD DVR. I don't expect miracles, but watchable would be nice). It looks like I may just wait for the 71 and 81 series this summer. The 71 will fix the blur problem, and hopefully the Oppo 981 problems will be fixed as well. And if I am lucky, Directv will deliver on some of their promises regarding additional HD channels, thus making SD less important (of course Samsung could satisfy millions of buyers by getting a better SD processor, but I don't see that happening). So, I will continue to watch, but I think waiting may be prudent,,,,not for the latest greatest "feature" but just for an acceptable unit.
52" Samsung 750, finally satisfaction
