I visited best buy for about the 3rd time in a week as I'm torn between the 47inch LM7600 and the 46" samsung d8000. The PQ on both the 7600 and 6700 LG's were pretty impressive. The 3d demos also seemed good, if not great.
The PQ on the 55" d8000 at best buy underwhelmed. Finding nemo on DVD, however could be the reason for the lack of clarity/ etc.
lastly, i tried out the 3d on the es7500 and wow, terrible. absolutely terrible. only marginally better with the glasses than without. I think possibly the battery for the glasses had died, but BB had the glasses rigged up in this mechanism that possibly had the charger attached.
pretty positive i will be purchasing the LG after my latest trip to BB.
