I have the chance to get an Onkyo DV-SP405 for $30 from a friend. I currently have a Panasonic progressive-scan DVD going to my Westinghouse LCD. I've been satisfied with the TV's upscaling, but I'm wondering if I should take this chance at a cheap upgrade. The only advantage that really interests me is better upscaling. Will I even notice a difference? I've also thought about trying to sell the pair and get a Oppo 980. Any thoughts?
