That is about $50 so you can get a pretty good device. TP-link tends to be a low priced brand that still sells equipment most people say works well. Something like a wdr3600 should be in your price range. You may also be able to get a ASUS RT-N53. The Asus tend to be the most liked brand but this router does not have as many features as the tplink. You would need to compare and decide which feature you like/need the most.
a update...these are routers only if you need a actual modem/router combination its going to depend what kind of modem you need. Cable modem devices tend to be very expensive and ADSL ones greatly limit you choice of devices.
