it all depends on your type of house. whether or not you have thin walls, 2-stories on your home, etc. I have a $30 netgear wirless router, and it works great. There is not much difference in speed, because it all depends on your internet provider, but instead, higher priced routers can go through walls, etc. with more power. if your xbox is fairly close to where the router is going to be placed, i would reccomend the $30 netgear.
