Well if it has to be a issue then it might crop up at any time. If the issue crops up after an year then even the warranty wont cover it.
This is a very bad analogy. After one year, you would have used it for an year. There's a big difference.
@technofast - there is no way to know whether these are refurb or not. unless TVs have serial numbers and trackable online. Lots of sellers sell refurb as new and people hardly know. two of my friends bought refurb iPhones thinking they are new. An average user hardly bothers about that. Worst, you can get a tv, replaced with cheap components.
Check it's official price in US. If with import cost and shipping, what's its price. If there is still huge difference then it's probably a refurb, parts replaced or stolen one. When buying costly items from ebay, at too good to be true prices, then keep this in mind:
