I've seen some factory refurbished NADs (in this case T761 I believe) on ebay that went for about CAD 650 with 1 year factory warranty. It was from an actual electronics store -- Red Ball/Bull/something, although I'm not sure if they are an authorized NAD retailer (for warranty purposes).
BUT, if you are interested in NADs you shuold be able to score some nice deals with now as they have a new series of new HT receivers replacing the old 751/761 line. May not have all the toys taht comes with a Denon but stereo music should be quite a bit better
