i started with the lg 42ld520..... was not impressed with the picture (or anything about it for that matter) so i took it back. after getting my new samsung, i am glad i made that choice.
exchanged the LG for a samsung 46c670 (guy offered me a deal for 899.99... it was originally 1099.99). BEAUTIFUL TV. everything about it was simply amazing..... except the whole left side was washed out, so it was defective. my local store did not have any more in stock, so i had to drive 2 hours round trip to a different store to get a new one. For this extra driving, they gave us a free $50 gift card.
Upon returning home with my new 3rd new tv (also a samsung 46c670) i set it up to find yet another problem. the touch buttons were not labeled. i knew they were their from the previous tv, i just had no idea where because they werent labeled. Also, i found the labels on the opposite side of the tv, upsidedown. After wasting so much time on this, i wasn't settling anything less than perfect.
So, they offered me a deal on a different TV as a replacement since they did not have anymore 46c670 tvs in this area. they offered me the un46c6300 for just $999.99. So 100 bucks more for an LED, and we used the free $50 gift card they gave us. so i now have a really nice 46 inch samsung LED tv, and i believe my tv saga is finished =)
