You could always go the custom IEM route. About a grand, sensas, ultimate ears, or westones...
Then there's the leatherhead (L3000) and R10s.
Slightly down that path, I have a pair of sony CD3000s for sale that some people really like
That reads as "While jerking off, tmonk says 'I don't like your face'. He then continues to jerk off, and says 'I don't like your hair, and I don't like you.' Then he finishes."
The camo hat hating I really don't get. Big deal, he had a run of stupid hats made? It's hard work making money in audio. If he found a way to make it easier for him, more power to him.
Of course, the 4g mod price didn't change just because you buy it from ALO. This ALO hating is a bit extreme. He's not any worse than any of the other overpriced DIY cable makers (except zach, who barely makes cables anymore). I mean, Alex (ayt999) is certainly way more expensive.
That, and I'll be glad to provide any help you need. Best bet is to configure the router, then swap them once it's configured. If it doesn't work, swap back etc.
It's very easy to set up. If you write down the settings for your current router, it will be relatively painless to transfer those settings over to the airport. And then add the network file sharing feature.
Yes, the airport would replace your existing wireless router. It would then act as your network file server as well as a wifi router. And in the future, when you upgrade to 802.11N, you'll already be ready for it in your router.
