I found a Denon 4520 on eBay for a good price, and it was listed as being from Tucson. Sweet - so I contacted the dealer and asked (a) could I pick it up locally and save some cost on shipping, (b) are they an authorized dealer and, if so, what is their website, and (c) was it made in Japan for the U.S. market (i.e. was it grey market).
The response was very short and said that the price was as listed and there was no local pickup. The person clearly avoided the question about being authorized and if it was grey market, and no local pickup implies to be that it would be drop shipped from somewhere else. I asked again if the person is authorized (they specifically state on the eBay page to contact them for their website if interested in other products), so we'll see. My Spidey sense started tingling at the eBay page, and it increased at the response. I'll likely pass.
