Hi! I currently have a G3 Graphite imac, no airport card, connected to Verizon DSL with a basic Westell 6100. I am getting a G4 flat screen imac with no airport card. I would like to get a wireless internet connection for both of them and need some help.

For starters, I have to buy an airport card for both Macs, is that correct, whether I get an Airport base station or not? I'll also need to purchase a wireless router, which doesn't necessarily need to be an Airport base station?
