I've been an avid reader of this forum and appreciate the informative and intelligent feedback. I'm in the market for an a/v receiver and am considering Denon's flagship 5803. I've seen it listed on Ebay for as low as $1,500, which is a great deal given the $3,500 + MSRP price. BTW, I've also seen the Denon 9000 DVD player for as low as $500 on Ebay! My question is, has anyone had experience buying such expensive equipment from these, what I assume are, unauthorized dealers. And if so, what was the experience like, what are the risks, etc.? I'd also be interested to know how these places can list this equipment for so much less than the MSRP. Thank you very much for the feedback.
