I am looking to buy a Sony STR-DN1050 for a new audio system and saw one used at BestBuy that was returned but said nothing was wrong with it. It was about 100 bucks cheaper than buying a new one and was curious if the 14days return policy bestbuy has is worth buying it and taking it home to test out or if it seems to sketchy and should just buy a new one?
