Need Modem/Router

I've always connected routers to my modems when I need to use the internet on more than one computer and my video game consoles. However, many times I have difficulty finding a compatible router to use with my modem, such as my most recent router - a Linksys.

 

At my mother's office, I saw that she uses a Netopia model from the 3300 series and it acts as a modem/ router in one unit. I would like to purchase a model such as that to simplify matters, as opposed to connecting a router to a modem. However, the price of the model that my mother owns costs nearly $200. So, I was wondering if anyone knew of a good modem/router that is under $200?

 

Thanks in advance for any response.
