[quote name='RedSoxFaithful']Really, not that great a deal at all.
In actuality, the Microsoft Xbox 360 adapter is a waste of money. I own one of the ones from the original Xbox, and while it works fine, I really regret that I didn't realize that I could have gotten an alternative at a third of the price.
For instance,
this adapter from NewEgg is $15 less than this "deal". And
this one, from eCOST.com, is $20 cheaper, shipped. A quick Google search of "wireless gaming adapter" reveals many other cheaper possibilities. I would really recommend not wasting your money on Microsoft's first party adapter- it's overpriced, and just isn't notably better.[/QUOTE]
I myself use a Linksys WET610N (wireless ethernet bridge) with my 360. I still consider the Microsoft adapter a good product for most. If you buy one and don't need it later on, you can always resell it for $60-80. They always go quickly on Craigslist. The wireless bridges and non-Microsoft gaming adapters are indeed more versatile, but they don't resell as easily.
People should know there are alternatives like that Trendnet for less money, or the Linksys I picked up for a little more. My Linksys even offers wireless N... though I am still using wireless G. If you get a bridge, you can also hook it up to a switch or another router and use it with other devices.
If you just want the Microsoft adapter, anything under $80 is a good deal.
