Bought a nice Pioneer receiver $10 at a garage sale (new $500) but to do some intricate functions it seems I need the remote axd7551. It was probably sitting there on the lawn by the receiver, who knows...ugh. Anyway, other than trying eBay, any other ideas where to search for a used one? New ones are close to $150, but paying $10 for the receiver itself makes me not want to buy a new remote.
