If you ever find that your router breaks and you need to get a replacement then I would not go to a computer shop and spend way over the odds on a brand new one. Instead I would suggest checking out sapianet.com.
They stock new, refurbished & used cisco products such as routers, switches, phones, and even security software that is cheaper than you will get it for in a shop on your local high street or even from some internet sites.
