Wheres a good place to buy a router or a modem for my xbox 360?

I ume your asking about a router or a cable modem for your network? First I would try someplace like Fry's Electronics; stay away from Best Buy, their prices are too high. If you don't have a Fry's around you try Amazon.com, in addition to having a wide selection you can read reviews to help you make your pick. Keep in mind if you get a router you still need a cable/dsl modem.
