A $300 TV has absolutely terrible color, poor/milky blacks, awful backlight uniformity, and it'll probably shoot craps in 18 months. IMHO People often mistake a cheap price with a good value. A $300 dollar TV is cheap,but not nessecarily a good value. I, for one am willing to spend a little bit more on a quality TV, knowing I am enjoying a crisper, more accurate, less distracting image. Not to mention, it has a far better chance of lasting a long, long time.
Short example: I spent $2000 on a closeout Pioneer Elite Plasma in 2006.
My buddy bought a 42" Olivia LCD the same year for 600 bucks. It died in 2007. He then purchased a 50 inch Akai Plasma for $1000, that lasted almost 2 years. He finally ponied up the cash for a closeout Sony 52XBR6 in 2009 for $1800. That TV has been flawless for over 3 years. His running total: $3200. Cheap =\= Value.
I can agree with this. You get what you pay for. I'd stick to brands like Panasonic, Sony, lg, Samsung and sharp. There's a good chance these TVA will last years longer while having a better picture quality. I too got burnt from buying a no name brand fhat died on me after only 4 years.
