I'd say just get a D-Link or Linksys wired router for even cheaper... 20-40 bucks at Staples, depending on the day and what rebates are out. Wireless is enabled by default on every SOHO (Small Office / Home / Home Office) router sold, and that's a free ticket for anyone to use your Internet connection for their purposes.
It's dead simple. 99.9% of all cable companies use a modem-based authentication that you never see, so connect the router, connect the comps to the router... and happy surfing to you!
The thing is with wireless networking is that each comp needs its own wireless NIC (Network Interface Card), just like the wired 10/100 card you're used to plugging the network cable into. That can be another 50-100+ per computer, based on the brand and quality, speed supported (11Mbps, 54Mbps), etc.
Then you need to set the encryption and passphrases, then set that up on each machine identically so you can connect.
My recommendation is that if you can connect each easily with a cable, do it. You can't get any more secure than a wired network.
