I recently saw a Sony KV-34HS510 TV available on clearance for $1280. When I went to ask about it, the salesperson told me that only open box models were available (for about $1100). The dealer is reputable (Tweeter), but still, I'm hesitant to jump on this deal because it's open box. Any thoughts on buying an open box TV? Should I bite the bullet and buy it, or just keep looking?
