Hi digowon,
You can likely do a pretty good job of tracking a good deal down with a reputable dealer (ask if they are an Authorized dealer) using
this site .
You can search for either a product or a reseller rating. Excellent site.
If you want to explore refurb,
ecost has proven to be a pretty good source for quite a few on this board, including my self. The Denon stuff comes with a 90 day warranty and you can buy an extended warranty (pretty inexpensive). You need to check often - the equipment doesn't last long at those prices. Also, if you find something there, call and make sure they actually have it in stock. You can save some serious $$ here.
