I would get something with wireless AC..
LINKSYS EA6500 HD Video Pro AC1750 SMART Wi-Fi Router $119.99
NOTE - Refurbished The cheapest AC router yet.. ranks 5th on the smallnet builder website, if you don't mind it being refurbished.. otherwise its $179.99 BNIB
Router Ranker - Ranking - SmallNetBuilder
Also its only Wireless N and AC only...
I never had any luck with and dlink routers so I don't usually recommend or buy them myself
