We have always gone with the biggest, big and most expensive..unforturnately. I will say that our 62" Samsung has lasted along time, as long as my husband can keep replacing the color wheel and bulb. We have replaced three bulbs (so the picture shows up on the screen) and two color wheels. They are small parts, but play a big role in getting the picture on the screen. We have had this TV for 26 years, beautiful picture....HD. Now we are considering getting the LED smart TV. My hubby came in yesterday and said,....since technology was changing on these televisions so fast with 3D (waiting on this one until you don't have to wear the glasses). etc. He thinks he has decided to get the best unsmart TV and use our Smart "boxes"....hoolu, Xbox etc for streaming Netflix. He said we can change out the plug in units with all of the features you want and your television doesn't have to stay up with the changing features. So we will see. He does have a point. we have all these other "things" we plug into our TV that do all the Smart things they have now put in the television. He said he wants a good solid television that will last, doubt he will get one to last 26 years. Samsung has been a good one.
