This is the one I use. Make sure that Linux can see your Ethernet card.

I got mine from Tiger Direct, but they no longer have them. All of my computers are networked. My next printer will be Ethernet, so it will be as well.
Linksys also makes one called WET54G that probably works with Linux.
They are a few $$ more then the typical cheesy USB wireless that Windows needs, but considering all factors, Linux is still far more affordable to network. Once the bridge is set up, any other computer can plug into it and instantly get online.
If there is one out there for Wireless N, that would also be awesome.
One other thing, make sure that you use a battery backup for all wireless routers, bridges and your cable or DSL modem. That way, they won't get fried at the next electrical power surge and when the power goes off your settings will be preserved.
Battery backups are almost essential these days, even if Linux can't talk to them.
