For home wireless networks, a combination of WEP, MAC Filtering and disabling Broadcasting provides some pretty decent security. Also, be creative when creating your SSID. As in a good password, use a random combination of letters and numbers that make literally no sense...and remember it.

Is all of this fool-proof? Not hardly. But someone would really have to WANT to get onto your network pretty bad to get through all four of them. And if you're not a bank, or some other sort of financial institution, my guess is you'd be pretty safe.
