Just recently got a Xbox360, and I've been wanting to go online wirelessly with it. I already have a wireless router, but still need an adapter. I was wondering besides the official 360 adapter, what other kinds could I use? People told me to get a Linksys WET54G, but I can't seem to find it anywhere, and it doesn't show up often on ebay. If possible, I would perfer the adapter/bridge to be under $40. Other than that, I'm open to suggestions.
