I am hoping you guys can help me out with some quick advice. I'm looking at receivers and have found the unit I want at the local Tweeter store and at ecost. The prices are within 20 bucks, so that is a non factor. The unit at Tweeter has been a floor model for about 6 months now. The ecost unit is a factory (denon) refurbished unit. ALl things being equal, would you prefer to get a factory refurb or a floor model? I would prefer to buy locally, but I am not sure what sort of use or abuse a floor model sees. Thanks for the help.
