You can network 2 computers for a lot cheaper than what these guys are telling you. Get 2 internal network cards, they are about $20 each. And then a cheap network hub, also about $20. Run your cable modem to your main computer, USB is the easiest way. Then run your computers network cards to the hub and set up internet connection sharing on the main computer and you can share the connection. That is an easy way to do it, but there are many other options if you need to do it differently. I would like to try a wireless setup now that the prices are coming down. I see them on E-Bay for very low prices.
