Good wireless router for my XBOX 360?

[imported_cubby]

I am switching from DSL to cable and am getting a new modem. My old DSL modem has wireless built in, but the cable modem does not. They want me to pay monthly for it. My XBOX 360 will be in another room away from the router. Hooking it up to my computer is not manditory, but if I do in the future I want something decent. Price is a bit of an issue as well. Thanks for any help!
