I'm interested in buying a Denon 3802 and a CD changer. The prices I've seen from online retailers are far superior to B&M dealer prices, and, considering I live in the boonies, it's very difficult for me to physically get to a B&M retailer (especially in the winter). My question is...is it safe to buy from an online retailer? I've heard some reports that a warranty may not be eligible if not bought from an "authorized" Denon dealer. Is it worth the price difference to chance paying for a repair/replacement myself? Any thoughts would be appreciated. (also...if anyone has any recommendations on decent priced Denon CD changer--quality, etc.--I would appreciate input). Thanks.
