I wanna set up a wireless network in my home and I don't have the cash to spend on an Extreme Base Station. But I'm not sure what I want/need for a router? I know N is faster than G, but I hear a G Gigabit is better than N. I know there's also an N Gigabit, but that gets into pricey territory again and I dunno if I need it. Here's what I want to do: Keep my iMac hardwired to the router and set up a wireless network for my iPod Touch and my wife's Dell Laptop. I also wanna add an Airport Express upstairs so I can run AirTunes as well as theoretically use it as a wireless access point for my DirecTV DVR to download On Demand videos. (I know the Express can do both, but I don't know if it can be both at the same time.) Anyway, any and all help would be greatly appreciated.
