If you don't mind being ripped off sure....You don't need the cisco branded memory for your router regardless of what Cisco tells you. You can buy viking, or kingston memory that will do the exact same thing. Call some cisco re-sellers and ask them for the memory and tell them you don't want the cisco branded mem. They should hook you up at about 1/3 of the cost.
