What Cisco router to buy?

[dcxman 0]

Morning all!

 

I'm in the market to purchase a switched router. I was looking recently at the Cisco 1604R ENET 4 port router switch. I just need to set up a 3 class room (computer lab) environment using NAT. Will this do the job? I have been only using NT servers and Linsys Routers thus far to Route IP, so I'm not sure how easy the GUI will be to get used to for a Cisco router. I just want something easy to implement with security.

 

If this is not a good choice, I would much appreciate a recommendation.

 

Thanx in advance.
