It really depends how much the discount is. In general, I don't think the discounts on Sony Style for their outlet/refurbished TVs is that great. You can often find better deals in the stores, especially if you have some of the big discount stores in your area.
As far as quality, I don't think you have to worry there. I've bought dozens of refurbished items over the years. With one exception, the refurbished items have always been of equal quality compared to the new in box items. The one exception was (ironically) a refurb Sony SACD player from the Sony website.
The first one had a right analog output, the 2nd one was brand new but damaged in transit, the 3rd didn't work at all. After that, I asked for a refund.
If it ain't in HD, it ain't worth watching!
