Which wireless adapter should I get for my Xbox 360?

So, this christmas I’m hoping to recieve a wireless adapter for my xbox 360. I’m doing a little research so I know what to ask for specifically. I don’t want to go with just the standard little router that microsoft makes because I think I can get a better deal. Are there any adapters that won’t work and can it be Cat5 OR USB? Links to products that are cheap and work well are appreciated. Thank you and Happy Holidays!
