Thanks guys.
The Dlink 520+ looks cheap (in a good way), only it has that little knobby antenna which hangs out the back. No port from what I've found. But they also sell for 23.99+shipping on Ebay. So I may consider getting one and hacking up the antenna.
My original plan was Orinoco (or other rebrand), but all models I found require a PC card > PCI adapter to use. Which is an extra $35-$50.
The Aironet looks decent. But a little spendy.
Should have added a little background to my inquiry. I have an old car, 73 Dodge Dart. The radio antenna is bent, and needs replaced anyway. So I found a couple 12b+ WiFI antennas that look about right ..

Should be easy with a little modding.
Checking out THG now . lots of good info.
