I’ll give my 2c here. If having the absolute latest thing out there then spend the money for OLED. On the other hand, if you are like me and tend to buy new stuff every four or five years, why spend the extra $ when you can get a very good TV for less than half the price. We just got the TV below for my Dad at a great price and he couldn’t be happier.

The biggest reason I would say don’t fork out the money for OLED right now is you will probably end up with buyers remorse when that very TV technology is available for 1/2 the price in the next couple of years.
Anyway, whatever you decide is the most important thing to you, I hope you find something that makes you happy. Good luck!
