Best wireless router for xbox 360s and laptop?

I got an Xbox 360 slim, and a Toshiba Satellite laptop, and a Cannon printer. Im looking for a Wireless router under $100 that can run all 3 at once. I also want the router to be 2.5 and 5hz, i heard that is the best to get. Also one that i can run a cable from the wireless router to the xbox if i want to have it wired during my more intense online gameing for better performance, but then move it to another room when needed and have it wireless. I know little about wireless routers because i never needed one until i got my laptop. and now its aggravating having to unhook my xbox to get on my laptop online then vise verse. I have read all kinds of reviews, and one that may be best for one person might not be the best for me. Streaming HD fast aint much of an option fo me since i don't have the fastest internet speed, but in case i ever upgrade i want one that could handle it if needed. Also my xbox and laptop will never be more that 20 feet from the wireless router, and i don't have neighbors to steal my connection either. I hope all these details make answering this easier.
