This tutorial shows how one Arduino can send data wirelessly to another Arduino. This can be accomplished in a number of ways, but I am showing how do to it using these 315MHz RF Link modules. When I bought mine it cost $11.95, but the price has gone up to $13.95. There are probably much better choices at the $20 range - these RF Link modules can only broadcast from transmitter to receiver, as opposed to creating a network of inter-communicating microcontroller. But if you're fine with one-way communication across an open space, then the RF Link is fairly easy to use - you just pretend it's a physical serial connection. (if a "serial connection" doesn't sound easy to you, then have a look at this tutorial).
