I used to be real partial to the Sharp Aquos line. I bought one when they first came out, but it was only 26 inch. It's in the bedroom now, and looks and works just as well as the day I bought it back in 05-06. I was also a huge fan of Samsung.
But since, I've purchased some LG stuff, and it's all extremely good quality. My phone, computer monitor and TV are all LG. All of them are flawless thus far.
