The advantage of all the ones mentioned here so far in this thread are that they are available on the phone too, and you speak to someone who knows what they are talking about, not some telesales rep. Haggling also works wonders
Cwhelan, I ordered my "B" unit from www.ubid.com and had it shipped to my front door Fed Ex for under $750 US. I think they have it now for $699 US plus shipping. No problems at all, not even a scratch. Denon refurbs them to new condition and even gives a 90 day warranty on the unit. For the $150-$250 savings, you can afford to have it serviced 1x if something does go wrong.
