first wireless setup

Hello all. I'd like to set up a router that will connect my iMac (about 1 year old), my wife's PC laptop (about 5 years old), and our Wii. Will the ones that Apple sells work for all? What about the ones sold in Best Buy or other electronic stores? Which should I go with?

Thanks for any and all advice!

The Airport Base Station will work for all your wireless devices. You pay a little more for Apple but it's worth it.
