For the later 6th gens it's definitely different: they have push-button start, so the key fobs aren't just passive remotes, they ARE the key...NATS-enabled RFID remotes.
It may still be possible to find the key or remote (or both) on ebay...but they still need to be programmed--which is where the dealer's costs come from anyway.
So unfortunately, if you want the spare key, you're pretty much stuck paying Nissan's prices. It's partly a security measure (Nissan doesn't want everyone to have access to the NATS encoding systems) but that doesn't make a $300 key any easier to swallow.
