Please do yourself a favour and get a real modem.
I don't believe a router would necessarily be the best example. Routers (Cisco/Bay etc) are really nothing more than a computer running an operating system (IOS) and usually boot their operating system from a flash card (they can also boot from TFTP etc). The real advantage of a Cisco router is you can put boat loads of interfaces in the bigger routers and the OS is designed specifically for routing, not much more. In fact I believe the Cisco IOS is derived from a UNIX kernel and custom built commands for routing (I am embarassed that I don't know for sure without doing a search as I should know this). Other *NIX OSes can do a very good job of routing although they may not support all of the routing protocols (EIGRP etc). QOS is something that is included with later kernels along with kernel level access rules. And if you happen to have the source code for said kernel you can trim out all of the non-routing related fat and it performs very well. Large Cisco routers are certainly more robust but you pay for it too. The real advantage of a conventional (hardware if you will) router or firewall is reliability. Not OS reliability but hardware reliability. Since their intended purposes are specific you don't need unreliable devices installed such as hard drives, video cards etc.
The modem is a better example. Hardware modem for sure is a wise choice.
