Cisco Routers vs everyone else

I am implementing a new network and need to justify the difference between a Cisco 1700 Series router and small office router like a Netgear.

I have a CCNP and know that Cisco is a great product. How can I justify to the number cruncher that the Cisco is a better choice?

Here is my config:
12 users
T1 equivalent bandwidth
Will provide intranet to mobile employees using SSL/HTTP
FTP
Fortinet Firewall
VPN

I can buy a low end router for less than $250. What does Cisco give me for that extra $$$?

All good ideas are welcome.
