Suggestion For A Wireless Router

I am looking to purchase a wireless router in the near future. I was wondering if anyone could suggest one that is not expensive or maybe give me some specs to look for in a good wireless router. Thanks!


A little background info:

The laptops connecting to the wireless have windows xp pro.
The ISP is comcast.
Would like to get a router with a good range, so the wireless could be picked up in three rooms.
