A local dealer is offering the Denon DRA 697CI Receiver for $540.00, which is better than most online places, which offer it for $599.00. There is, however, an online dealer offering the identical piece for $399.00. They claim it's factory packaged, etc. Should I go for it? Any red flags waving out there? Seems strange to find it for 200 bucks less. I'm new at this and don't want to make a big mistake with my first gear purchase. Thanks for your help.
