If you wanted to save some money, you could set up one of your computers to act as a router, but you would have to have it on all of the time if you wanted the other machine to be connected to the internet. Basically to do this, you would need two network cards in one machine. Connect one of the network cards to your cable/adsl modem or whatever. If you have either win2k or win98se, it has the software built in. Just install the internet connection sharing addon from ADD/REMOVE programs if you are using win98se, in win2k it is built-in and can be activated by looking in the network properties box. Then connect the other network card to a hub, and you are set.
