This is my old router, in perfect working condition.  I replaced this with WRT54GL so I could load Tomato firmware.  I originally paid $129 on 3/21/06.  This router works with all standard b/g cards.

I'm not sure if there is any custom firmware that you can load on this router or not, I really haven't looked.  The picture is too bright on the picture to see what version it is, but I believe it is v1.  I am posting this from work, so if anyone is interested in the version number I can get it as soon as I get home.
