What is the best 2 in 1 router and modem

Hey guys, I have $100 and i'm looking to buy a 2 in 1 router/modem. I'm turning to the awesome community of the Tek once again for your opinions. 

 My house is about 1800 square feet and my internet speed is 30MBPS down and Up speed is 6 MBPS. Any suggestions? 

Cable my good sir. 


No suggestions?
