I have an emac and a 1st gen iMac I have started thinking about networking the two after getting cable internet service. I have been told by salesmen that I should use the airport for doing such a task, but the airport just seems to be way to expensive to me. Is some other way that I can network my macs without the airport? Maybe something wireless? and also, how do i route the cable modem to both macs? I would really apreciate your help.
