I have posted on another forum but I'm hoping I can get more responses/help here. I have been researching and researching and researching. I thought I had my model picked out 3 different times only to change. I am just sick of reading reviews and specs. I thought this would be an enjoyable thing to do but now I am feeling worried and stressed out that I am going to make a bad decision, waste money or be stuck with something not good. I have had a 42 inch Hitachi Plasma I bout in early 2006. I want something to replace that. Its going to go above the fireplace in the family room on a articulating dual arm wall mount. I would guess that viewing distance will average 10-12 feet with some seats off at maybe a 40-45 degree angle. I have DirecTV as the viewing source. 1. Panasonic TCP55ST60 Plasma is what I had my mind set on for about a month. Have read lots of good reviews on Amazon and CNET. I have had a 720p plasma and have enjoyed it very much over the past 7 years with no issue. I figure with one that old and never having IR issues why would the new styles bother me? Well, you do read some reviews with those complaints so maybe it's user error/abuse? I'm not sure. Also only 2 pairs of 3D glasses and I have read that the 3D is just ok on this set. $1448 PRICE 2. Samsung UN55F7100 LED. Looks awesome! Very great reviews as well. I was in Costco over the weekend and saw a model # UN55F7450A. Not sure if these are comparable or not. I'm thinking they are and the model #'s are different because its a Costco only model? Again, not so sure. I was BLOWN AWAY with the picture color and clarity. Also comes with 4 pairs of 3D glasses and I experienced that in store. WOW AGAIN! $2179 PRICE Now, is the Samsung worth almost $700 more dollars? Is the LED "better" than the plasma? is viewing the LED from the way my family room is set up really going to affect the picture quality to the point where it's bad? I also have read reviews on a SAMSUNG UN55F7500. Not sure of the main differences. Just more "smart" features? If so, I really don't need that I don't think. I mean, I do have an Apple TV which lets you do Netflix, stream photos, youtube etc. I'm just hoping some people on here can educate me and help clear my mind so I can make a good decision. ***By the way, also will be running the sound through a Polk Audio sound bar with wireless sub. Model # 9000IHT.
