Where Can I Find A 60 inch Brand Name HDTV For $400-450

Solution
for that price you're only going to find things like vizio televisions or perhaps floor models which are heavily discounted.
60" at that price? And you want a brand name one? You'll probably have more luck trying to buy it used on eBay or craigslist, and even then you'll probably need to get lucky. If you're in the U.S., you might want to keep a look out for Black Friday deals (unsure if Black Friday is a thing internationally), because there is no way you'll find it retailing at that price otherwise.
